Document 8: 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.
