Pierre-Emerick Aubameyang has revealed what has been frustrating him at Arsenal since he joined the club in January.

The forward has been left annoyed by the ruling that does not allow him to compete in the Europa League for Arsenal.

The club host AC Milan, where Aubameyang’s career started, on Thursday, with the striker ineligible to play.

Aubameyang featured for Borussia Dortmund in the Champions League during the first-half of the season, which means that he is not able to play for Arsenal in European competitions until next season.

With Alexandre Lacazette currently injured, Danny Welbeck is Arsenal’s only available striker for the clash – which Arsenal are 2-0 up on aggregate in.

Speaking to The Mirror, Aubameyang said this:

I am really frustrated because the rules are a bit… I don’t know how to say in English, but I am disappointed because I can’t help my team;

That’s life. I have to deal with it.

The Gabon international also recently revealed that Arsene Wenger was the reason behind his decision to join Arsenal.

He has scored three goals in five Premier League games so far for the club.
