Sir Bobby Charlton is convinced Cristiano Ronaldo will not regret returning to Manchester United.
After twice declaring a desire to quit Old Trafford for Real Madrid - both before and after his involvement in Wayne Rooney's World Cup dismissal - Ronaldo checked in as planned for pre-season training on Monday.
While there was time for no more than a brief meeting with Rooney, the pair will probably be team-mates again in Amsterdam at the weekend when United tackle Porto and Ajax in the annual four-team tournament.
And, once the dust has settled on the summer controversies, Charlton feels Ronaldo will accept remaining at Old Trafford was the correct decision.
'Cristiano wants to be successful,' said Charlton. 'The more he thinks about it, the more he will realise he is in the right place.'
However, Charlton does accept Ronaldo may have to run a gauntlet of abuse at the start of the season, having been singled out as public enemy number one for his part in England's World Cup demise.
Alan Shearer and Frank Lampard have both publicly expressed their disgust at Ronaldo's behaviour and Charlton believes the player himself would now admit he was wrong.
'I think Cristiano realises he has made a mistake which he will have to pay for,' said the former England skipper.
'I am sure the fans will have a little go at him at the start of the season.
'He is only a young lad. He is inexperienced and doesn't know a lot about the game. But he will come back better because of this.
'It is going to be tricky for him at the beginning but he is a great player and that is what people should focus on.'
Meanwhile, Charlton insists United have not been forced to pay over the odds for new signing Michael Carrick.
The England midfielder will make his first public appearance as a United player this lunchtime following a move from Tottenham that could end up costing the Red Devils an eye-bulging £18.6million.
While most Red Devils followers are acutely aware the club's midfield needs strengthening, the general feeling is the sum paid for Carrick is far too high for the 25-year-old - who has made only seven appearances for England - especially when Ruud van Nistelrooy has been sold to Real Madrid for just over £10million.
However, Charlton predicts any worries over the price tag will be quickly erased as he is sure Carrick is destined to be an Old Trafford star.
'Michael Carrick is a great player,' said Charlton.
'Once he has played his first game I don't think anyone will consider the price we have paid.
'The deal is justified because we want the best.
'He is the type of player we have needed, he is English and I don't doubt for a moment he will be a big success at Manchester United.'
