Sir Alex Ferguson is the best man to sort out any row between Wayne Rooney and Cristiano Ronaldo.
That is the view of former Celtic boss Martin O'Neill as speculation mounts that the Portuguese international could be ready to leave Old Trafford amid the furore over his role in Rooney's World Cup dismissal.
Asked about the issue on BBC Radio 5 Live's Sportsweek programme today, O'Neill said: 'Do I think the two of them can work together? Absolutely.
'If all the things we have read about the incident are even remotely close to the truth, then a little apology from one player to the other to begin with....
'My own view is that if both players are worthwhile keeping in your team, that they are going to make a difference throughout the season to your side, then why not?
'If one of the players wasn't all that fantastic, then I think your job is made slightly easier. You can tell him to go. But I actually think that both can work together.
'What do you do on the first day of training? I think you would have to lighten the mood, to be perfectly honest.
'There will be a few weeks now after the World Cup is over before Manchester United meet up, and I think there might be a time of reflection for both of them, and I honestly think that they should put it to the side.
'But listen, why are you asking me this question? One of the greatest managers of all time should sort that problem out, and I don't think he's had too much difficulty in the past.'
O'Neill's comments came just hours after Ronaldo revealed he hoped to leave United for either Real Madrid or Barcelona after admitting his disappointment at the lack of support he has received from his current employers following Rooney's red card.
Reports have suggested he and the England striker have already resolved their differences.
