Hello and welcome to LIVE coverage of the BIG ONE*. It's Arsenal v Manchester United! (*admittedly, today's game is a squabble over fourth; in yesteryear, these two heavyweights contested the title. How the mighty have fallen...)

That's it, full time. Arsenal did well today, and were ultimately dominant winners. United were weakened from the start, and didn't chase the game when they went behind. Wenger has his first win over Mourinho in the league after 13 attempts.

Martial wins a corner on the left. He takes it short, Rashford dinks one in, it comes to McTominay, and he angles a volley at goal, with Cech well behind.

There wil be at least three minutes of added time..

Arsenal are confidently probing for a third.

Rashford sends a long pass into space on the right for Martial to chase, but it's nowhere near him.

McTominay is on to replace Mata.

Welbeck and Oxlade-Chamberlain off in place of Giroud and Bellerin.

United win a corner on the right wing. Lingard dinks a ball in from the edge of the box and Koscielny clears it away.

Well done, Noz.

Rooney has a bang from 30 yards this time, and it arcs nicely, but it's well over the bar this time.

Oxlade-Chamberlain thinks he's beaten Darmian, but concedes a foul. Mourinho is on to manage sarcastiically now, bringing on McTominay to chase a game. He doesn't give a solitary one.

Arsenal are content in possession now, happy that they're in control against previously talented rivals.

Coquelin is on, Xkaha is off with what seems a minor injury.

Rooney receives the ball outside the box, and he curls an effort a foot over the bar.

United seem to be happy to let this one slide, at this point. It's not worth the hassle of injuries to push it. Having said that, this Arsenal side could fall apart with the merest prod.

Ozil shrugs off Rooney, and whips in a tempting ball that Welbeck can't quite reach.

Monreal tackles Rashford from behind but the ref doesn't care. They do often just make it up as they go.

Xhaka tries to find Ramsey breaking down the right. Carrick sticks out a leg to boot it in the air, and Tuanzebe fails to shield the ball out of play. United tear back, and the move ends with Xhaka blasting wide from distance.

Kosciely goes into the book, and Mata has the chance to curl one in from the right.

Lingard wins a corner on the left for United. Rooney swings it in to nobody, and Arsenal break down the middle.
