Arsenal defender Mikael Silvestre is looking forward to their Champions League semi against Manchester United.
"I still have a lot of friends [at United] but it's part of the competition," said Silvestre, who missed much of last season with knee ligament damage. "You go to a match and you want to fight, no matter who you play against."
"You have to fight even if it's your best friend in front of you," the France international said. "When you have to tackle, to win the ball, when you have to play the challenges, you fight for your club and you forget everything else."
