Andrew Thatcher: #Arsenal fans must question why many players like Walcott, the Ox, Ramsey, and Wilshere spend more time injured rather than playing

Paul Collins: Marcos Rojo is the best defender in the world... at passing back to his own goalie. Wow.

Arsenal on top since the break I reckon. Every time it comes to Danny Welbeck the move breaks down though. He's struggled on his Old Trafford return.

The crowd getting edgy now. The 100mph tempo of the first half has slowed to more like 70, but the mistakes keep coming in midfield. Olivier Giroud is warming up for Arsenal, can he get on and replace Danny Welbeck maybe?

"Good save from De Gea in the end. Composed goalkeeping as it just took a deflection from Alexis Sanchez's shot."

Oooh, dreadful touch from Chris Smalling opens the back door and Santi Cazorla dives through it. He runs in on goal and finds Alexis Sanchez on his left. Sanchez shoots but it takes a big floaty deflection and is easy for David De Gea.

Shane Daly: This game will have a later winner, hopefully it will be a United goal.

Martin McNamara: Pundits are saying this is an entertaining game? Well if you like pub football where no-one can string 5 passes together!

Lawrence Brooks: Phil Jones coming on to take the set pieces #philosophy

John in Doncaster: "For the first time in ages, Arsenal have a better bench than Man Utd."

"I have some sympathy for Oxlade-Chamberlain. He never seems to stay in the team long enough because of injuries. He showed in the first half what he is capable of."

Wayne Rooney has been finding himself all over the field in recent weeks when operating as a midfielder, but he's done all of his work in the Arsenal half this evening. It's paid dividends so far...

Aaron Ramsey is on for the stricken Alex Oxlade-Chamberlain. Theo Walcott is also warming up.

Alex Oxlade-Chamberlain stretches and twang goes the hamstring, Marcos Rojo finds Wayne Rooney and heads wide on the stretch. Oxlade-Chamberlain is done here I reckon. You can't run off a torn hamstring.

"With Phil Jones going in to centre defence it gives more speed in that central area. United struggled a couple of times in the first half when Arsenal played ball in to that central area."

Michael Carrick's first rangefinder is bang on the money, an arcing 45-yard pass out to Ashley Young on the wing. Hector Bellerin in a mess under it, as comfortable as Monty Panesar taking a steepling catch at long on.

Bellerin misses it altogether and he's lucky that Young doesn't take advantage.

"I think the change in midfield is tactical. Herrera was struggling up against Cazorla a couple of times in that first half. I think it must be an injury to Luke Shaw, there was nothing to suggest he was struggling through poor form."

Angel Di Maria earns a nice round of applause after beating two men on the wing. This is the best he's played for a while. The crowd start the second half a bit quiet, that first 45 was pretty taxing on the old vocal cords though.

Marcos Rojo will move to left-back, Phil Jones at centre-back. Here we go!

Luke Shaw will have plenty of time to look at his boots Pete, as he's been hooked at the break as part of a double change. He's replaced by Phil Jones, with Michael Carrick on for Ander Herrera.

Former Manchester United keeper Peter Schmeichel to BBC Sport: "Both teams look nervous, the individual mistakes are incredible. Luke Shaw needs to look at his boots. He has been sliding all over the place and giving Arsenal space."

"I think United have looked quite composed. I think Louis van Gaal will be fairly happy with this. Get the ball forward a bit quicker, especially to Wayne Rooney and they will be in the right areas."

Here we go, the teams are back out of the tunnel. More of the same please, more of the same.
