Manchester United striker Marcus Rashford is well aware of the challenge that awaits them from Arsenal tonight in the Premier League

Under new coach Unai Emery, Arsenal are unbeaten in their last 19 games in all competitions and arrive at Old Trafford on the back of three straight wins.

And Rashford, who famously scored his first league goals in United’s 3-2 win over Arsenal in 2016, knows much has changed since then.

“It’s a game that holds a special place for me, playing against Arsenal at Old Trafford,” Rashford told the club website.

“But it’s almost a different Arsenal side now, they’re playing better football, they’re a more aggressive team and looking at them now they’re one of the strongest teams in the league.

“We have to take all that into account and no matter what happens we have to try to get the three points.”

United have only won once in their last four games and sit eighth in the Premier League table after 14 games.

Now Rashford admits they need a response following a disappointing 2-2 draw at Southampton on Saturday.

“It was disappointing and we paid the price for not starting how we should have started,” said Rashford.

“We grew into the game, especially in the first half when we were creating chances and starting to play better football.

“But we can’t expect to start games in the way we did that one and get three points. We have to do better.”

The United-Arsenal game will begin at 21:00 (CET) tonight.
