The former Arsenal forward wore the armband for Louis van Gaal's side at the World Cup, whilst Robben was undoubtedly the best player for Oranje.
And despite appearing harmonious on the field, the pair were embroiled in a feud over the captaincy.
According to the Mirror, Bayern Munich winger Robben has been accused of trying to take over as leader, apparently frequently referring to the squad as 'MY boys'.
The paper reports that Robben often led team-talks for the Dutch and believes he was the side's real leader given a flurry of inspirational performances.
The battle of egos left van Gaal in an uncompromising position, although the incoming United chief stood firmly behind van Persie's captaincy credentials.
“Van Persie gave a great team talk before the Costa Rica quarter-final. He has been a brilliant captain, a great leader," said van Gaal. “You are all making false suggestions.
“When you have a captain who can speak for you that is worth more than anything a coach can do. It really comes across to the players."
Appointing the former Feyenoord youngster as captain is not without risk, however.
Having only been at the club for two seasons, some players who have plied their trade in Manchester for longer may be disappointed to be overlooked.
Yet the forward's credentials were boosted further with the added backing from team-mate Dirk Kuyt: “People forget how hard Robin had to work to make it to Brazil. He does’t deserve this.”
