Arsenal's new signing has a cynical touch about him! Gabriel chops across the run of Adam Reach for a stonewall yellow card.

"Patrick Bamford has had no impact playing much wider than he would have liked. I don't think Lee Tomlin looked very pleased either when he went off."

Lovely touch from Mesut Ozil to dance inside the defender, he connects well enough with the strike too but it's right at Tomas Mejias.

Middlesbrough make a double sub, Patrick Bamford and Lee Tomlin off, Jelle Vossen and Adam Reach on.

"Lee Tomlin has tried to find space behind the striker but has found no space at all. Mathieu Flamini has been all over him. There are a few players in the Boro side that can play that number 10 role, like Patrick Bamford, but at the moment it's Tomlin.

"He should go and have a look at the guys on the other side - Cazorla, Sanchez and Ozil. Wonderful players, but if you are going to play in that role you have to put the effort in as well."

More great play - but once more the finishing touch is awry. It's Danny Welbeck again, beating the last man to run on to a lovely lay-off but as the keeper came out he poked it wide.

I don't want to start a campaign against the man but that's another poor finish...

Good persistence from Calum Chambers down the Arsenal right but his final ball is not up to scratch. If Arsenal get an early third then this could be an avalanche. Middlesbrough look tired, they are absorbing wave upon wave of attacks with no counter attack to speak of. Lee Tomlin and Albert Adomah - both excellent in the win at Man City have been snuffed out of the game.

Danny Welbeck! No, no no. Another lovely move comes unstuck at the feet of the England man. Alexis Sanchez and Mesut Ozil combine with some intricate stuff but Welbeck gets the ball under his feet.

Roy Hodgson is still going to pick him as his number nine isn't he?

What a comment from our man Franklin there. Genius.

Arsenal are under way as they attempt to chisel away at Boro in the second half.

Alistair Wiseman:, external Giroud = 10 goals in 15 games this season. Arsenal are maybe one man short defensively from being very, very good. Gabriel maybe?

That could be as open a cup draw as I can recall. It's anyone's to win. But Arsenal are looking very good.

As it stands, here's how the FA Cup draw will be looking tomorrow night:

1 LIVERPOOL

2 ARSENAL OR MIDDLESBROUGH

3 ASTON VILLA

4 WEST BROMWICH ALBION

5 BRADFORD CITY

6 BLACKBURN ROVERS

7 READING

8 PRESTON NORTH END OR MANCHESTER UNITED

You can see Olivier Giroud's goals at the top of your screen. Just click on the 'highlights' tab.

The first one is as neat a move as you will see.

"Completely controlled by Arsenal. You could see the game plan from Boro but it hasn't worked. They changed things but that has not worked yet either.

"Arsenal are dominant. At the moment, the last word you would use to describe Arsenal's performance is jittery.

"They need one more goal, but after that they can do as many flicks, nutmegs and tricks as they like."

Steve Wilson
BBC Match of the Day commentator at Emirates Stadium

"Arsenal are 45 minutes away from the last eight of the FA Cup. Santi Cazorla's been pulling the strings, Alexis Sanchez has been at the heart of things, and Olivier Giroud on the end of it twice. Arsenal have been good."

If there's a weak link in the Arsenal attack at the moment, it's Danny Welbeck. Again he shanks a shot well wide after neat build-up play. Alexis Sanchez, Mesut Ozil and Santi Cazorla have been first-class.

Bradford boss Phil Parkinson, speaking to BBC Sport: "I am obviously delighted with the way we played. We did the right things in the right areas of the pitch. Defensively we were outstanding today. I was pleased when Jon Stead put that second goal in, it gave us a bit of breathing space and we saw the game out professionally.

"There is always a danger because the expectancy might have been we would win this one after beating Chelsea but we have kept that underdog spirit. It was a good, old fashioned cup tie, a really good advert for the FA Cup.

"The pitch was not as bad as it was two or three weeks ago, we played some good stuff at times, so did Sunderland.

"After today we would like another game at home. It is incredible for all the players to experience that sell-out atmosphere. We had all three sides singing and behind the team and it raises the lads to the next level."

"Boro's passing was really impressive at the start of the game but in the last three or four minutes it has not been great. Maybe the two centre-backs are a bit more jittery having been put under a bit of pressure."

Arsenal have been very impressive so far this afternoon. Purring along.

Sunderland boss Gus Poyet, speaking to BBC Sport: "It was a proper old style cup tie. Two teams committed. It would be a mistake, or a deflected shot that would be the difference from the two teams, or a decision from the referee.

"Somebody thinks for a minute that the players did not try their best, but they adapted to the pitch and went for it. They needed that bit of luck. The referee had a clear view of the penalty [on Steven Fletcher] and didn't give it. Unfortunately, Kevin Friend again did not give us what we deserved and it became a tough task from then.

"Credit to Bradford, they know how to play these games. It is not humiliating, it is what the cup brings into the equation. If the top teams always beat the smaller teams, then the cup would not exist.

"I have no problems [with the angry chants from Sunderland fans], I get on with my life. It is normal, I am responsible. I have no issue with the fans. I never hide and at the end of the day I am the one who will pay the price because the one who can get sacked is me."
