The Manchester United defender was inches away from being left red-faced during the pre-season friendly against Sampdoria last night (August 2).

Video shows him play a lazy back-pass to goalkeeper David De Gea, who is a completely different position.

The Spaniard is forced to scramble across the goal and dive to palm the ball away before it crosses the line – conceding an indirect free-kick for a back-pass in the process.

But the Serie A side hit the huge wall of players and Man Utd immediately counter.

Manchester United's Daley Blind almost scored an own-goal just before his team went 1-0 up

A surging run by right back Antonio Valencia sees the ball then come to Henrikh Mkhitaryan.

His deep cross finds Matteo Darmian, who fires in another cross that the Armenian then gets on the end of to give Man Utd the lead in the blink of an eye.

Red Devils fans were quick to joke about Blind’s luck.

“Calculated by Blind,” wrote one.

Another added: “lmao what a sequence of events.”

“Blind did live up to his name with that back pass.” commented a third.

New signing Nemanja Matic won the hearts of the fans after comforting a woman when he accidentally hit a ball at her face.

It comes as ex-player Phil Neville backed Jose Mourinho’s men to pip Manchester City to this year’s Premier League title.
