Rio Ferdinand insists everybody at Manchester United will need to prove themselves under new manager David Moyes – no matter who they are or what they have achieved.

Ferdinand retired from international football on Wednesday to focus on his United career, but understands with Sir Alex Ferguson’s reign ending on Sunday, nothing is guaranteed. Every manager has different ideas as you will see Moyes’ tested on the main sports¬†betting sites.

Still in search of an FA Cup medal, the 34-year-old recently won his sixth Premier League title with United. He believes that every member of the squad will be starting again when Moyes takes over.

Speaking to MUTV, Ferdinand said: “We’ve got to prove ourselves to the new manager. He’s going to come in with new ideas, new rules, a new regime.

“No matter how long you’ve been here, whether it’s the likes of Giggsy or myself, we’re going to be in the same boat as people like Danny Welbeck, Phil Jones, Tom Cleverley.

“We have got to make sure he feels we’re the right people to start each game.”

During the awards night at Old Trafford Ferdinand revealed how Ferguson announced his retirement to the players, describing the response as a hushed silence, but accepts the timing of his departure is fitting after achieving the club’s 20th league title.

“He broke the news to us and the thing I remember most is that it was dead quiet in the room, a mad silence,” he said.

“It was just a combination of disappointment and respect for the manager’s decision, and for what he’s done for us as individuals and as a team.

“[Winning the title] is the way the manager would have liked to leave the club in his dreams, not looking up at other teams but saying ‘come and catch us’.”
