Marcus Rashford failed to set the world alight in the final 20 minutes of Manchester United's 2-2 draw with Leicester City on Saturday.
Red Devils fans were quick to point out the mistakes made by the 20-year-old, who failed to set up Romelu Lukaku to score late on in the game.
He instead attempted to take on Kasper Schmeichel and go for goal himself, but the great chance to extend Manchester United's lead came to nothing.
Jose Mourinho then saw his side concede a late goal through Harry Maguire, meaning they came away from the King Power Stadium with a single point.
Discussing certain decisions made by his Manchester United team after the game, Mourinho said: "You know some players they have childish decisions and time helps them to have maturity and to decide better."
"But some other players they stay with childish decisions until the end of their career.
"It depends on what is inside [points at head], and depends on the way they learn and they don't learn."
Red Devils supporters were equally annoyed following the game, and apparently focused much of their frustration at Rashford on social media.
