How many chances do United want??

This one falls Bruno Fernandes way as Boro give the ball away in their own half, but the Portuguese midfielder drags his effort onto the post.

United in again but just cannot find that second goal.

Marcus Rashford from the angle laces an effort which Joe Lumley bats away.

Boro fans making all the noise noise.

Marcus Tavernier is booked for halting Paul Pogba's gallop forward.

Looking at the replay from a pitchside camera, referee Anthony Taylor was looking directly at Duncan Watmore and clearly sees the handball but fails to blow his whistle.

I was in the overwhelming majority in the stadium in expecting that to be ruled out.

Stuart Attwell the VAR, Neil Davies his assistant.

Lee Dixon on ITV: "Watmore's touch wasn't the best and he controls it with his hand. It has to be given as handball. If that was a defender it would be a penalty.

Without it hitting his hand, the ball was going away."

Terrible defending from Manchester United I have to say. Really, really poor goal to give away from Manchester United's point of view.

Dean Henderson sort of stopped, tapping his arm claiming handball.

Think everyone felt that was going to get disallowed but was surprisingly given.

You can clearly see Duncan Watmore, the ball has popped up and hit his hand as he sets it up. It hits his hand, oh my gosh he has given the goal. I don't believe it. You can clearly see as the ball comes into the box!

Change for Middlesbrough.

Former United youngster Duncan Watmore on for Folarin Balogun.

Another opportunity for Cristiano Ronaldo, another miss, heading over from Luke Shaw's cross.

Just ticking into the hour mark.

United lead but have failed to take numerous chances to end the game.

Middlesbrough at still in this.

This is Middlesbrough's best spell of pressure in the game.

This time Folarin Balogun has space in the area but his attempted cutback bobbles into the hands of Dean Henderson.

First save of the night for Dean Henderson and it is stunning.

Boro carve United open at the back, Isaiah Jones finds the run of Matt Crooks inside the area, but the midfielder's effort at the near post is brilliantly tipped over the bar by the United's goalkeeper's reflex save.

Ronaldo is just having one of those nights, it goes to show that we all have them!

However it wouldn't surprise me if he does score because of his workrate and endeavour - he keeps getting those opportunities.

Cristiano Ronaldo finally hits the net...but the wrong side!

It's just not happening for the United forward, taking Marcus Rashford's low cross first time but thumping wide.

That's poor from Marcus Rashford, meeting Jadon Sancho's cross in the box but side-footing wide from six yards out.

He should really be doubling his side's lead.

Just noticed Harry Maguire is wearing bright yellow boots.

A centre-back should NEVER wear coloured boots, particularly ones that bright.

United still stroking the ball around confidently, they're in a different league to Middlesbrough.

Literally.
