Chelsea have two genuine VAR grievances now. Maguire should have seen red and the original foul for Zouma's goal was a push by Fred on Azpilicueta.

No wonder their is a sense of real injustice around Stamford Bridge.

Fred pushes Azpilicueta, it's absurd! That was the initial offence...what can Azpilicueta do?

It's crazy stuff. I think Stockley Park need their heads banging together.

'It's not football any more' is the chant from the Chelsea fans and I'm inclined to agree to a large extent.

It's been an entertaining second half though!

That's a big call. Fred shoves Azpilicueta into Williams - the goal should stand. That's ridiculous! Wow. You have to question what Stockley Park are seeing there?

Fred is booked, as is Kurt Zouma.

It's kicking off now. Kurt Zouma takes out Anthony Martial and Fred gets involved. Feisty!

Martial is down, will ref Anthony Taylor get involved here?

Right let's clear this up. It's not a goal.

Brandon Williams was pushed in the back at the near post by Cesar Azpilicueta before Kurt Zouma hit the volley into the back of the net.

BUT Fred clearly pushed Azpilicueta first! The Chelsea captain could do nothing but collide with Williams. He was shoved.

That is another awful decision by VAR.

NO GOAL.

They're checking for a foul...

You just sense a bit of anxiety among the Chelsea fans in the stadium. Not been a great start to the second half and United have been the better side in the opening exchanges. They've just got to hang on in there, try and get a foot hold in the game and make some passes.

Ah well played! Mason Mount takes the ball on his chest on the edge of the area and rattles a left-footed shot against the face of the post, unlucky!

The whistle had gone for an earlier handball so it wouldn't have counted but that's better...

A bit more info to give you on the decision not to send Harry Maguire off for what appeared to be a kick out at Michy Batshuayi.

The Premier League says the VAR officials reviewed the incident but did not deem it to be violent conduct, so no red card.

Son Heung-min was dismissed for a similar incident when Tottenham played Chelsea in December - a match also officiated by referee Anthony Taylor - but both are classed as subjective decisions, and this time VAR Chris Kavanagh decided in Maguire's favour.

You can see United have started the second half with a real purpose and energy. This would be a huge win for them to come here and get three points.

Real air of frustration from the home fans now. They can't get it going.

So, to recap, here's the draw for the quarter-finals that was made a few minutes ago on Radio 5 live.

Crystal Palace or Brighton v Birmingham City

Bristol City or Everton v Chelsea

Arsenal or Lewes v Coventry United or Tottenham

Leicester City or Reading v Manchester City

Stephen: Bruno Fernandes is always asking for the ball, he's bold and brave with his demands to be in possession, he has nice technique and does pretty much nothing with the ball he's always screaming for.

Neither side have men in the middle as they put crosses in one after the other. Get Odion Ighalo on!

Clever from Bruno Fernandes who just flips the ball around Antonio Rudiger, runs into the defender who gets booked.
