an older player, you need that towards the end of your career."
With Everton boss Moyes coming in to take charge, Ferdinand admits he, like all his team-mates, will need to impress all over again and start from scratch.
"You've got to prove yourself under the new manager," he said. "He's going to come in with new ideas, new rules and a new regime. No matter how long we've been here, and the likes of Giggsy and myself have been here for many years, we'll be in the same boat as people like Danny Welbeck, Phil Jones and Tom Cleverley. So we've all got to prove ourselves to make sure he thinks we're the right people to start each game."
In the same MUTV interview, Rio reflected on a whirlwind week for the Reds - beginning with the moment when Sir Alex Ferguson informed the players of his impending retirement.
"We came in and there was a notice on the board to say there was a meeting," Ferdinand revealed. "There were rumours in the paper that the manager was going to leave but we were thinking: 'There's no chance he'll be leaving. There are too many good things going on at the club because of the squad he's building'.
"Then he broke the news and the most I remember from it was that it was dead quiet in the room. Even when he left, there was real silence and I think that's just a combination of disappointment and respect as well for the manager's decision. For what he's done for the club, for us as individuals and as a team, you've got to respect his decision. He's been in the game for a long time, he knows what he's doing and I think he deserves a rest."
The atmosphere has since been celebratory of course, from Sir Alex's fitting send-off at Old Trafford to the Premier League trophy parade, during which Rio led the chants and singing on the bus and generally savoured every moment of the latest league triumph. The defender admits some fans might have seen a new side to some of the players.
