The Frenchman admits he is still hurting after being overlooked for a place in last season's FA Cup final, due to the emergence of left-back Patrice Evra.
Speaking of his FA Cup final omission, Silvestre told the News of the World: "Alex Ferguson knocked on my door at 11am on the morning of the game to tell me I wasn't playing.
"Can you imagine how that felt? He did his best to dress it up saying I hadn't played a lot in the run-up to the game, I was still coming back from injury and he wanted to keep me fresh.
"I didn't want to here it. I didn't expect to be dropped and it was a huge blow."
