Full credit to Middlesbrough. They have been brave in the second half and got the goal. The one major talking point from that second half performance was the Middlesbrough goal. You can clearly see Duncan Watmore has brought it down and it clearly hit his hand.

If Manchester United go out of this cup tie it will be a major talking point.

Stephen Wilkinson: Why is it not considered that the handball is absolutely integral to the goalscoring opportunity? Without the handball the chance is gone and possibly even goes out for a United goalkick. Awful decision.

Beth: Supporting Man Utd is tough. We should have won this in the first half.

Henry Ellison: All of our shots apart from Sancho’s goal have been right at the keeper. Aim left or right please dear god

Luke Shaw into the box but elects to pass instead of shoot and the chance is lost.

It's nailbiting stuff for ex-United boss Sir Alex Ferguson up in the stand.

Time is ticking away, we're approaching territory in which goals scored are named after him.
