Manager Jose Mourinho said Luke Shaw used "his body with my brain" during Manchester United's 1-1 draw with Everton and has told the club's young players they need to "grow up" quickly.
Defender Shaw, 21, made his first appearance since January on Tuesday night and it was his injury-time shot that led to the penalty from which Zlatan Ibrahimovic equalised.
"He was in front of me and I was making every decision for him," said Mourinho.
"He has to change his football brain."
On Monday, Mourinho questioned Shaw's commitment and focus.
