Right now?
I'd take a defensive coach any day of the week. You have to start off by being organized, well structured and difficult to beat, before you play the pretty stuff. Once that foundation is there, you can mix it, especially in a league like the Prem. This is not South America or Spain, where technical stuff, passing and possession is the priority, and where you get time on the ball. The fast paced and physical nature of the premiership should be taken into account.
Trying to outscore the opposition with the purest form of attacking football you'll ever see with a 'you score 3 we score 4' attitude is a failure, when you can't do simple things like defending setpieces, or having the well trained discipline to defend as a team.
Wenger is trying to emulate Barca, but without the hard work that goes with it on the training pitch. Watch their workrate off the ball, and then watch ours![]()
