Spot on Matelot.
Wanderers have been playing that way for a couple of seasons now and it's definitely more entertaining but the approach is not without problems...
* playing out from the back can be nerve shredding at times especially if the opposition have a good high press or your defenders can be hustled into making mistakes
* when you have a lot of possession, the opposition tends to fall back into a low block so then it's a job to pick out goals against a packed well organised defence and that can be very frustrating
* beware the fast counterattack - you definitely need pace at the back to cover the breaks
Our main criticism of Evatt is that it's one thing to try to play the Barca/City way but you need Barca/City quality players to execute it properly - and we can't afford them so it can be worrying and frustrating at times.
That said, your lot looked comfortable with it last night and I think you'll be fine - but I bet my bottom dollar that you'll encounter all three of the above issues at some point. Everything will depend on what solutions Kompany has up his sleeve.
