Manchester United crashed out of the FA Cup as Championship side Middlesbrough came from behind at Old Trafford and then emerged victorious in a nail-biting 16-shot penalty shootout.

Young striker Anthony Elanga ballooned his shot over the bar to give Chris Wilder’s side a win that was celebrated in enthusiastic fashion by a 9,000-strong visiting support.

United will complain about Middlesbrough’s controversial equalizer, scored by Matt Crooks, who tapped home despite Duncan Watmore clearly handling in the build-up.

However, they only had themselves to blame after failing to take numerous chances in a game where they had 30 shots at goal, the clearest of which came when Cristiano Ronaldo missed a penalty in the first half.

Jadon Sancho seemed to have put United on the road to the last 16 when he marked his FA Cup debut with a goal.

Instead, United’s most realistic chance of silverware has now disappeared.

The draw for the FA Cup fifth round will take place at 11:40 GMT on Sunday.
