Former Manchester United striker, Dimitar Berbatov, has identified the club’s big problem under their current manager Ruben Amorim.

Amorim suffered his first defeat as Man United manager on Wednesday after his side’s Premier League 2-0 defeat against Arsenal at Emirates Stadium.

Two goals from Jurrien Timber and William Saliba gave Mikel Arteta’s side all three points against the Red Devils.

Reacting, Berbatov admitted that Man United’s big problem is ‘set-pieces’.

“I admit that in the second half, the storm was there for United,” Berbatov said on Amazon Prime.

“Ruben Amorim said earlier that a storm was going to come for his team and it came tonight.

“The set-pieces were a big problem for them and Arsenal scored twice from them. Now it’s back to the training ground to fix the mistakes.”
