I wouldn't say Aubameyang is that good. At Arsenal he has played poorly recently to say the least, and I don't think he will strengthen Barcelona. No, maybe he'll play up at Barcelona, start showing a level, maybe he's just tired/he's tired of playing in England? Maybe, but personally I don't believe in him yet. In any case, better him than nothing
Exactly, I know that and that's why Arsenal don't need him anymore this season. I know the stats that Aubameyang has had this season at Arsenal and it has dropped a lot compared to the previous few seasons. He is no longer able to play at the high level he was a few seasons ago, but I still believe he can help Barcelona score goals this season.
Aubameyang has only played 14 times this season at Arsenal and has registered 4 goals and 1 assist. He's not done yet and maybe he can improve his form at Barcelona if he's really needed by a team that's been in a slump this season. I hope he can prove it well because his first game is getting closer.
