Question: Who was Thomas Helveg's coach just before he helped win the 999 Serie A championship

full_context: Document 1: 1993–94 A.C. Milan season: Associazione Calcio Milan won three trophies during a successful 1993–94 season, most memorable for the 4–0 victory against FC Barcelona in the Champions League Final in Athens. That game saw a goal explosion from a Milan side that had been extremely defensive during the entire league season, which in part caused the Italian Football Federation to introduce three points for victories starting in the autumn 1994. Milan won Serie A with a mere 36 goals scored in 34 games, but conceding a mere 15, which meant they had the defensive line, with Franco Baresi and Paolo Maldini as key players, to thank for their third consecutive domestic success. Milan's match against struggling Reggiana at San Siro on 1 May 1994 came on a day when the sporting world was overshadowed with the death of racing driver Ayrton Senna in the 1994 San Marino Grand Prix, but the football world was focused on AC Milan's attempts to seal a 14th title. It was a narrow 1–0 defeat for Reggiana, with a goal from Massimiliano Esposito, but enough to seal the Scudetto.
Document 2: 1996–97 Udinese Calcio season: Udinese Calcio had its best season since the days of Zico in the club during the 1980s. With goal scoring trio Oliver Bierhoff, Márcio Amoroso and Paolo Poggi on top form, Udinese finished fifth, even troubling the top three in the standings. Bierhoff and Poggi scored 13 goals each, while Amoroso hit the back of the net on 12 occasions. Despite the sensational results, coach Alberto Zaccheroni remained at the small club, while 1997–98 looked set to become a further improvement for Udinese.
Document 3: 1993–94 Serie A: The 1993–94 Serie A was won by Milan, being the 14th title for the "rossoneri" and their third in succession, complemented by glory in the UEFA Champions League. It was a disappointing season in the league for Inter Milan, whose 13th-place finish saw them avoid relegation by a single point, but they compensated for this by winning the UEFA Cup. Piacenza, Udinese, Atlanta and Lecce were all relegated. A.C. Milan's visit to struggling Reggiana at San Siro on 1 May 1994 came on a day when the sporting world was overshadowed with the death of racing driver Ayrton Senna in the 1994 San Marino Grand Prix, but the football world was focused on AC Milan's attempts to seal a 14th scudetto title. It was a narrow 0–1 defeat for Reggiana, with a goal from Massimiliano Esposito, but enough to seal the "Scudetto".
Document 4: 2009–10 Genoa C.F.C. season: Genoa C.F.C. had a mixed season, in which it struggled to replace world-class striker Diego Milito, who moved on to Internazionale, where he was key in it winning the treble in 2010. Such a player was difficult to find on the market, and his Argentinian replacements Hernán Crespo and Rodrigo Palacio lacked the final punch. Crespo had it in his younger years, of course, but despite four goals in the autumn, he was offloaded to Parma, as Genoa put its faith in David Suazo for the goalscoring. Sergio Floccari also departed, and the Lazio signing scored more goals for the Roman club in half the year than what any player did for Genoa the whole season, while Suazo became a flop. The defence did not perform at expected level either, and even though the team scored several goals by many players, the defensive holes ensured the team did not repeat the fifth position from the year before.
Document 5: Thomas Helveg: Thomas Lund Helveg (born 24 June 1971) is a former Danish professional footballer who played as a defender for Odense Boldklub in the Danish Superliga, with whom he won the 1989 Danish championship. The most prominent period of his career was five years with Italian club AC Milan, with whom he won the 1999 Serie A championship and 2003 UEFA Champions League tournament.
Document 6: 2002–03 Udinese Calcio season: Udinese Calcio bounced back from the hugely disappointing 2001–02 Serie A season, in which it only just managed to avoid relegation. Under new coach Luciano Spalletti, Udinese gathered strength, and was a constant feature on the top half of the league table. Even though the squad lacked the goalscoring punch, the defence led by Néstor Sensini and surprising goalkeeper Morgan De Sanctis held it together to such a degree it finished sixth in the league. Also Czech signing Marek Jankulovski impressed, the Napoli signing switching form left-wing to left back, causing interest from several bigger clubs. In the offence, Udinese's most influential player was David Pizarro, who scored seven times from the midfield and grabbed the attention from Lazio, who tried to sign him and teammate Martin Jørgensen immediately after the season had finished. Undisclosed Lazio players refused moving to Udine as compensation for the transfers, and both stayed on, much to the relief of Spalletti.
Document 7: 1995 UEFA Champions League Final: The 1995 UEFA Champions League Final was the 40th edition and took place in Vienna between AFC Ajax and A.C. Milan. It was Milan's third consecutive European Cup final, a feat which has only been matched in the Champions League era by Juventus between 1996 and 1998, and they were aiming to tie Real Madrid's record of having won the European Cup six times. After 85 minutes the deadlock was broken when Frank Rijkaard, a former Milan player found Patrick Kluivert with just enough space in the penalty area to lose his two markers and slot the ball past Milan keeper Sebastiano Rossi.
Document 8: 2008–09 Genoa C.F.C. season: Genoa C.F.C. enjoyed its best season in recent history and finished fifth in Serie A. Topscorer Diego Milito hit the back of the net 24 times, and earned a move to Inter prior to the 2009-10 season. The ex-player and 29-year-old Argentinian Milito, arrived from relegated Spanish side Real Zaragoza, and the returnee performed his best season yet. Thanks to his goals and Thiago Motta's midfield display, Genoa finished in the top 5, and nearly pipped Fiorentina to the final Champions League spot. Motta was also sold to Inter in the summer, which left a huge fold in the Genoa squad.
Document 9: Demetrio Albertini: Demetrio Albertini (born 23 August 1971 in Besana in Brianza) is the sporting director of Parma and a former professional Italian football midfielder and vice-president of the Italian Football Federation (FIGC). He is widely considered as one of the legends of the A.C. Milan side of the 90s and a fundamental player for the Italian national team of the same period. He spent most of his career with Milan of the Italian Serie A, winning many trophies, including five Serie A titles and two UEFA Champions League titles with the club. He also played his final season for FC Barcelona, winning the Spanish League before retiring that year.
Document 10: 1998–99 Udinese Calcio season: Udinese Calcio only faded a little bit compared to its club record-breaking 1997–98 season, in which it finished third in Serie A. With topscorer Oliver Bierhoff, midfielder Thomas Helveg and coach Alberto Zaccheroni all departing for Milan, Udinese was looking to be on the back foot prior to the start of the season.
Document 11: Peter Schmeichel: Peter Bolesław Schmeichel MBE (] ; born 18 November 1963) is a Danish former professional footballer who played as a goalkeeper, and was voted the IFFHS World's Best Goalkeeper in 1992 and 1993. He is best remembered for his most successful years at English club Manchester United, whom he captained to the 1999 UEFA Champions League to complete the Treble, and for winning UEFA Euro 1992 with Denmark.
Document 12: 1997–98 Udinese Calcio season: Udinese Calcio sensationally finished third in Serie A, much due to Oliver Bierhoff being in the form of his life, scoring 27 goals in a league season consisting of just 34 matches. Bierhoff, coach Alberto Zaccheroni and winger Thomas Helveg all left for Milan at the end of the season, ensuring Udinese had lots of work to do to stay at the level it was.
Document 13: 1989–90 A.C. Milan season: A.C. Milan won their second consecutive European Cup, thanks to a final victory over Benfica. The Dutch trio of Marco van Basten, Ruud Gullit and Frank Rijkaard was now a firmly established unit, but their efforts were not quite enough to defeat Napoli in the title chase.
Document 14: 1989–90 Serie A: 1989–90 of the Serie A was another dominant year for Napoli, with Diego Maradona being among the leading goalscorers in Serie A (16 goals), behind Marco van Basten of Milan (19 goals) and Roberto Baggio of Fiorentina (17 goals). But while Baggio's Fiorentina narrowly avoided relegation, Maradona's Napoli won their second Serie A title in four seasons, while Van Basten helped Milan retain the European Cup as compensation for their failure to win the Serie A title, having finished two points behind Napoli. Demoted to Serie B for 1990–91 were Udinese, Verona, Cremonese and Ascoli.
Document 15: Paolo Maldini: Paolo Cesare Maldini (] ; born 26 June 1968) is an Italian former professional footballer who played as a left back and central defender for A.C. Milan and the Italy national team. He spent all 25 seasons of his career in the Serie A with Milan, before retiring at the age of 41 in 2009.
