Hello and welcome to Eurosport's live commentary from the Premier League fixture between Manchester United and Arsenal.This is Nick Royle (@nickaroyle) taking you through all the action from Old Trafford.

Ramsey picks out Sanchez with a fine pass but Rojo is across to make the tackle.

CHANCE: Sanchez heads wide from the edge of the six-yard box following a short corner involving Elneny and Ozil and a Walcott flick-on.

This has been a good start from United - though Sanchez then comes alive and wins a corner following a snapshot and a deflection off a red shirt.

Mata draws a foul from Elneny, and the Spaniard takes the free-kick himself, but his effort drifts past Cech's far post.

Martial is unable to clean header on goal following a good move involving Valencia and then a good cross from Rashford.

A good move between Martial and Rashford breaks down.

Mourinho gives the Arsenal fans a wave, after the away fans sing where he should head off to!

We are off at Old Trafford, with Arsenal in yellow shirts and grey shorts, Manchester United in their usual red home kit. Herrera hauls over Sanchez early and concedes a free-kick in the centre circle.

Both sides coming out from the tunnel, to the sound of the Stone Roses' "This Is The One."

Arsenal's only Premier League away defeat in 2016 came at Manchester United in February, and that home defeat to Liverpool was their one reverse in their last 21 top-flight matches.

Manchester United have taken 18 points from their opening 11 games, their third worst start to a Premier League season. Arsenal are unbeaten in 10 PL games (W7 D3) since losing 4-3 at home to Liverpool on 14 August.

"I think I have won against every manager in the world during my 20 years here and I do not make of this game a competition between two managers,” he said. "It's between two clubs and two teams and I think I can understand that people want to create controversy, but it's not that that makes the audience. What will make the audience is the quality of the game."

Wenger has played down the tensions between him and Mourinho, which reached its nadir when he shoved the then-Chelsea manager during a 2-0 defeat at Stamford Bridge in October 2014.

Arsenal have lost seven and drawn two of their last nine Premier League games at Old Trafford, but the North Londoners did beat United 2-1 in the FA Cup sixth round tie in 2015.

Arsene Wenger's only win in 15 previous meetings with Jose Mourinho was the 2015 Community Shield victory over Chelsea. The Portuguese has never lost a Premier League game against Arsenal, winning five and drawing six of his 11 previous meetings with the Gunners.

Cazorla has yet to return to training following the Achilles injury he suffered in the Champions League victory over Ludogorets on 19 October.

Bellerin is out for four weeks following an ankle injury sustained in the North London derby, while Santi Cazorla misses out with an Achilles problem. “Hector is out for four weeks, he was injured in the last ten seconds against Spurs with a strong tackle from Danny Rose,” Wenger said.

MANCHESTER UNITED: De Gea, Valencia, Jones, Rojo, Darmian, Carrick, Ander Herrera, Mata, Pogba, Martial, Rashford. Subs: Romero, Blind, Schneiderlin, Lingard, Young, Depay, Rooney.///ARSENAL: Cech, Jenkinson, Mustafi, Koscielny, Monreal, Coquelin, Elneny, Ramsey, Ozil, Walcott, Sanchez. Subs: Ospina, Gibbs, Gabriel, Xhaka, Iwobi, Oxlade-Chamberlain, Giroud.

Alexis Sanchez, who played 84 minutes and scored twice for Chile against Uruguay in World Cup qualifying on Tuesday despite suffering a hamstring problem earlier in the international break, starts at Old Trafford in the lone striker role for Arsenal.

Arsenal manager Arsene Wenger has made three changes to the side that started the 1-1 draw with Tottenham at the Emirates Stadium on 6 November. Carl Jenkinson replaces the injured Hector Bellerin at full-back, while Mohamed Elneny and Aaron Ramsey come in for Granit Xhaka and Alex Iwobi in midfield.
