Especially in the Champions League Arsenal lacks mentality and they lose in experience to Bayern Munich because it was proven that they had so much difficulty when facing the German giants. If the problem is in the front line then for the Premier League they will also experience the same thing but the front line they have is quite productive in scoring goals.
I think they are just used to the premier leaguestyle of playing... they tend to perform better in premier league maybe because they've studied almost each team pattern and style of playing by competing with them frequently...on the other hand they are not used to the Bundesliga style that's why champions league is a hard one because it brings together different league teams with different playing styles
"Premier League style" my foot. Every league has its own personality, its own rhythm. The Premier League? Its fast, its tough, its always a battle. Arsenal plays to such advantages. Thats wise, not some slavish adherence to English customs. Not that they dont need a lethal striker who can finish with authority. They are unstoppable once you give them that. Bayern had luck in escaping. Arsenal possesses the management and the talent. They just need that final piece of the puzzle. And be careful once they have it. Whatever league, whatever style, they will dominate. You can bet on that.
