Ferdinand wrote for the London Evening Standard: "Wayne Rooney won't feel like this right now but being left out of the Manchester United starting line-up could be the best thing that has happened to him.
"I know what it feels like. It happened to me at United and I remember feeling bitter and thinking it was a disgrace. But I refocused and the hunger and spark came back.
"This is a great time for Wayne to re-evaluate his game, his training-ground routine, his methods off the pitch and at home and how he gets ready for a game.
"I am sure he will be able to recharge mentally and physically to go again."
