Document 7: 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.

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.
