Manchester United boss Jose Mourinho gave the club's junior players a lift this week.
The Sun reports he made his impromptu appearance before the youngsters set off to play in Mourinho's homeland of Portugal.
Some of the Reds Under 14 and Under 15 players are involved in a celebratory match against Benfica's academy side and Mourinho wanted to offer his good wishes.
Said Tour leader Les Parry: “He was brilliant, he came in and spoke to the boys like adults, answering some really well thought-out questions.
"The boys didn't know he was going to come in so to see their faces when he walked through the door was wonderful.
"The most pleasing thing was the length of time he spoke to the players for, he didn't come in just to show his face, he gave the boys quality time and quality information.
"I think the staff were just as in awe of him as the players were!"
