DC United coach Wayne Rooney was happy to be back at Carrington last week.
Rooney set tongues wagging when he turned up at Manchester United's training HQ in a club tracksuit.
But the real reason for the Old Trafford legend's flying visit was to watch his lads Kai, 12, and Klay, 9, training with United's academy.
DC United boss Roo was back in the UK following the end of his club's MLS season, says The Sun.
The former England international's American outfit finished bottom of the Eastern Conference with just seven wins from 34 matches - although Rooney did not take over until July.
But he is now enjoying the off-season as he watched his boys follow in his footsteps.
