Italo Galbiati (born 8 August 1937 in Italy) is an Italian football coach and former player.
 He is a trusted assistant to Fabio Capello having worked with Capello at AC Milan, Roma, Juventus, Real Madrid and England national team.
 He has also managed AC Milan himself on a caretaker basis, and is currently an assistant manager to Capello with the Russia national team.
Peter Rösch (15 September 1930 – 12 January 2006) was a Swiss football defender who played for Switzerland in the 1962 FIFA World Cup.
 He also played for BSC Young Boys, Servette FC, and FC Sion.
 He later managed Sion, FC Martigny-Sports, and FC Épalinges.
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.
Mirosław Dreszer (born 28 August 1965 in Tychy) is a Polish former football player who played goalkeeper.
 He began playing for GKS 71 Tychy; he played in the Polish First Division in the 1984–85 season, and played for Legia Warsaw in the 1985–86 season in two matches.
 In 1984, he started as the goalkeeper for the Polish U-18 national team, which finished in third place in the European Championship.
 He then moved to GKS Katowice where he played for the next five seasons.
 He played a total of 57 matches in the Polish First Division season of 1990–91.
 During the final of the European Cup Winners' Cup in the 1986–87 season, he suffered a serious injury against Swiss team FC Sion.
 The injury was caused by FC Sion striker Dominique Ciña and Dreszer later required a surgery to recover.
The 2011–12 FC Sion season started on 16 July 2011.
Gennaro Ivan "Rino" Gattuso, (] ; born 9 January 1978) is an Italian football manager in charge of A.C. Milan Primavera and a former footballer.
Marco Pascolo (] ; born 9 May 1966, in Sion) is a retired Swiss international football goalkeeper who spent his best playing days at Servette FC and FC Zürich in the 1990s and early 2000s (decade).
 He is currently goalkeeping coach for FC Sion.
In the 2012–13 season, Sion competes in the Swiss Super League and the Swiss Cup.
 In the summer transfer window, they brought in Italian World Cup winner Gennaro Gattuso, as well as Kyle Lafferty (former of Rangers).
 In addition, they bought an until then unknown Brazilian footballer called Léo Itaperuna from the 5th division Club of Arapongas and another forward Mathieu Manset from Reading.
The 1990-91 season saw Sampdoria win the Serie A title for the first time in their history, finishing five points ahead of second placed AC Milan.
 Third placed Inter Milan were victorious in the UEFA Cup, with ninth-placed AS Roma compensating for their sub-standard league season with glory in the Coppa Italia, while Juventus's seventh-placed finish meant that they would be without European action for the first season in three decades.
 Lecce, Pisa, Cesena and Bologna were all relegated.
Tiago Daniel Rodrigues Dias (born 4 May 1998) is a Portuguese professional footballer who plays as a forward for A.C. Milan Primavera in Campionato Nazionale Primavera.
