Manchester United star winger Nani is convinced Manchester City will struggle should they sell Carlos Tevez this month. Nani, 24, was a team-mate of Tevez at Old Trafford.
He told The Sun: "I played with Carlos and he is an important player for any club.
"I don't know if he will stay at City but, if he does go, it will be a big problem for Mancini because of the way that he plays and his experience.
"The Community Shield is the first official title of the season and we want to win. And facing City makes the match more exciting.
"It's also our first derby of the season, so to lift the trophy would raise our morale and inflict pain on our rivals."
