Rio Ferdinand believes Arjen Robben should have already signed for Manchester United.
As reported by the Manchester Evening News, the ex-Red Devils defender has insisted that the club should have sealed his signature 10-years ago.
The Dutch winger, who is currently starring at the World Cup, has been hailed by Ferdinand as the player of the tournament so far.
The Bayern man has been linked with a £40 million switch to the Theatre of Dreams in recent time, but Ferdinand believes he should already be playing for the club.
Ferdinand, speaking in the Mail on Sunday, said: "Arjen Robben has been the outstanding player of the tournament for me so far, and not for the first time I’ve being thinking 'if only' about the missed opportunity Manchester United had to sign him when he was young.
"He should have been a United player. He would have fitted in.
"He had a brilliant breakthrough season with PSV in 2002-03, a campaign in which he turned 19, and Sir Alex Ferguson wanted to sign him.”
The winger ended up completing a move to Manchester United's Premier League rivals Chelsea, before eventually being sold to La Liga giants Real Madrid.
And Ferdinand recalls that his former boss wasn't prepared to pay over the odds in order to land the Dutch wizard.
He continued by saying: "United made a bid of something around £5m, and Sir Alex was always determined he wouldn't over-pay for any player.
"When that was rejected, Chelsea paid something like £12m."
With Robben currently firing for the Dutch national side in Brazil, it's no surprise that his international coach wants to take him to Old Trafford ahead of next season.
Manchester United's wingers struggled for form throughout the previous campaign, and it remains to be seen as to whether the new United boss can land the Bayern ace in this summer's market.
Fans of the Red Devils will certainly be excited by the prospect of Robin van Persie and Robben playing in the red shirt next season.
