In July 2010, Cavani signed for Napoli. The transfer, however, was a loan of €5 million plus an option/obligation to buy outright for €12 million, which made the total fee €17 million. After debuting for Napoli as a substitute in the previous game, Cavani scored twice in his first start, as Napoli beat Elfsborg in the UEFA Europa League 2–0 and qualified for the main tournament. He then started his Serie A tenure with Napoli in spectacular fashion, scoring a controversial goal against Fiorentina after just seven minutes, with replays showing the ball hardly crossing the line. Cavani also scored on his home debut against Bari before adding a late winner against Sampdoria, meaning he had scored in his first four competitive matches with Napoli.
