He's been in the Premier League for almost two decades but he's still really struggling when it comes to that jacket!
Arsenal are having a pretty good time of it in the Premier League at the moment, especially after their 3-0 thumping of Watford which sent to them to second place.
The Gunners have managed to solve a few of their problems on the pitch and got Mesut Ozil to turn up and put some performances in.
However, things are very much the status quo on the touchline, as Arsene Wenger has come up against his old nemesis once again.
No, not a red-faced Sir Alex Ferguson or Jose Mourinho... he's having a nightmare with his jacket! It has almost been a year since Puma finally decided to give Wenger a jacket that he can zip properly - and he looked delighted about it.
Sadly, however, he's still managed to fall foul of one of the toughest tasks a human can face... putting a jacket on without too much trouble.
He faced the same old problems once again after Arsenal beat Watford but this time the zip wasn't the issue. In fact, he struggled with the arm and the hood!
C'mon Puma, please help Arsene and give him the best birthday present ever: reward him with a good jacket that actually works.
