Manchester United head coach Reuben Amorim has issued a stern warning to his team ahead of their Premier League clash against Arsenal.

Mikel Arteta's side will host the Red Devils at the Emirates Stadium on Wednesday night in what will be Reuben Amorim's fourth game in charge.

Amorim began his campaign with a 1-1 draw against Ipswich Town before recording back-to-back wins against Bodo/Glimt and Everton in the Europa League and the Premier League respectively.

As the Portuguese tactician gears up for his biggest test against Arsenal, Amorim believes his team will have some difficult moments during their campaign.

“I want to say different things, but I have to say it again: the storm will come,” Amorim said about his side’s progress.

“We are going to have difficult moments and we will be found out in some games.

“And I know that, because I’m knowing my players and I know football. So I understand the difference between the teams.

“We are in the point that we are putting simple things in the team, without training. And you feel it.”
