These are the result from last matches between arsenal vs PSV
Arsenal 1-0 PSV
PSV 2-0 Arsenal
These clubs are equal. It's hard to pick which club that will be able to perform better during the group stage. I don't wanna mention lens and sevilla caused by im still waiting for them to make their miracle.
The possibility for the result of this group is arsenal or PSV will be on the first and second position.
Im also anticipating the comeback that can happen from lens and sevilla which are still struggling to solve their internal problems.
Honestly I don't think these teams are really equal. Because that was the Europa League before anything else. Arsenal wouldn't show the same performance there and in the Champions League. The Champions League is the most prestigious tournament in Europe and I will be expecting Arsenal to care about it the same as the Premier League.
Therefore I think Arsenal will win their home game against PSV by at least two goals. Maybe the game in Netherlands would be tougher but I still expect Arsenal to play way better than the last game between them there. Arsenal can collect 6 points against PSV in my opinion.
