Cristiano Ronaldo has warned Angel Di Maria of the responsibility he faces in filling the number seven shirt at Manchester United but has backed his former teammate to rise to the challenge.

Di Maria moved to Old Trafford for a British transfer record fee of £59.7m and will follow in the footsteps of George Best, Bryan Robson, Eric Cantona, David Beckham and Ronaldo in wearing the famous number.

The number's significance was lost somewhat following Ronaldo's move to Real Madrid in 2009 when Michael Owen and Antonio Valencia wore it, but the world player of the year believes Di Maria is ready to fill the void.

Speaking after the Champions League group stage draw in Monaco, Ronaldo said: "I wish the best to him, he deserves it, he is a fantastic player, he is going to do well at Manchester United.

"And I said to him: 'Number seven is a big responsibility', but I think he will be able to take that shirt because he is a fantastic player."

Di Maria has been officially unveiled by his new club and could make his debut against Burnley at Turf Moor on Saturday afternoon. Much of the debate surrounding his arrival in Manchester has focused on where Louis van Gaal will choose to play him as the manager continues to fine-tune his new 5-3-2 formation.

The Argentine international thrived playing on the left of midfield during Real Madrid's Champions League-winning campaign last season, but Di Maria insisted he will play wherever his manager tells him.

"It depends on the manager –where he wants to put me and where he wants me to play," Di Maria said, through the club's official website. "I have come here to work for the team and I am prepared to play in any position.

"I am very pleased with the manager for choosing me to come here. United have already won many trophies and are a very big team. I come to help the team, raise their game and also be an important team once again. I want to win many trophies."
