Arsenal do finally put a cross in, it bounces inside the six-yard box and Alexandre Lacazette pushes Luke Shaw into the post.

Arsenal going out with a whimper.

And if you missed them, here are Lukaku's two assists:

There have been some good performers. Paul Pogba has had a good 45 minutes. But my man of the match is Romelu Lukaku.

Those assists in the first half helped shift the momentum Manchester United's way. I was impressed by his application and attitude on the right-hand side.

Manchester United have managed this game really well. They are coasting into round five now.

Now or never for Arsenal. For all their possession they haven't looked like scoring too often in this second half. Sergio Romero was last tested in the 72nd minute.

Matteo Guendouzi is booked for taking down Paul Pogba, who has been an absolute weapon on the break in this second half. In a good way.

TEN MINUTES ADDED ON!

Into the final minute of the advertised 90 - how much more time will be added on though? If Arsenal get one now there could be more intrigue to come...

It looks like a coin was thrown at Jesse Lingard in that melee on the touchlines which goes some way to explaining why he lost his cool a touch. No need for that whatsoever.

Lingard is a lucky boy there, as he has got involved to try and look after his mate and got embroiled in a scenario and had a conversation with Arsenal fans and lost his head a little bit.

Plenty of Arsenal fans have already decided to make their way out. Ther will be lots of time added on.

Ole Gunnar Solskjaer now makes a pragmatic change, replacing Jesse Lingard with Phil Jones.

Bristol City reach the fifth round for the first time since 2000-01.

Despite a positive start for Bolton, who led after just six minutes, it's 23-year-old Niclas Eliasson's superb individual goal that seals it for Lee Johnson's side.

Chelsea loanee Kasey Palmer was a number of young Robins players to produce encouraging performances in a deserved victory against struggling Wanderers.

After all that it's a booking apiece for Marcus Rashford and Sead Kolasinac. Jesse Lingard was in the thick of that and he's already been booked. Lucky man?

Oooh hello it's all kicked off now! Marcus Rashford and Sead Kolasinac put their heads together and then everyone steams in. Loads of pushing and shoving, VAR is getting involved...

It's just bounced in front of Cech. When you are diving to your right if you are going to get your hands on it you want to knock it away, but he's knocked it straight into Anthony Martial

Manchester United haven't dominated this game but they have perhaps been rewarded for a positive mindset. Send on two strikers and one of them scores...

It's been the story of the game. They've been waiting for that moment. Paul Pogba has been driving through the heart of the Arsenal midfield time after time. His shot bounces before it gets to Petr Cech and it's an easy tap-in for Anthony Martial. You feel that could be tie over.

Bristol City are looking to see this one out at 2-1 after a relatively quiet second half.

The in-form Robins are heading for a sixth win on the bounce, but Bolton's miserable run looks set to continue as we enter stoppage time at Ashton Gate.
