A year later, in January 2010, Belletti was linked with a move to Flamengo in his native Brazil, but the Blues rejected their offer. In Chelsea's game against Preston North End in the FA Cup fourth round, Belletti hobbled off the ground with a knee injury just 20 minutes in and was replaced by Florent Malouda. On 27 February 2010, Belletti was sent off for a professional foul on Manchester City midfielder Gareth Barry to concede a penalty, a match City won 4–2 at Stamford Bridge. Belletti came on as a substitute in the final game of the 2009–10 Premier League season, where a Chelsea win ensured they won the title. A week later, Belletti came on as a substitute for the injured Michael Ballack in the 2010 FA Cup Final against Portsmouth. Despite committing a foul which that gave Portsmouth a penalty, Belletti was ultimately on the winning team as Chelsea won 1–0.
