I think the very best managers, for the top clubs, identify what they need, work to get it quickly and try and have it done before pre season.
Wenger at times struggles with the concept of balance. Great we bought Sanchez, and Debaucy, however we let Sagna, Jenko and Vermalen go.

Midfield is the biggest example yet of the complete lopsidedness in the way Wenger thinks. Yet he knows we need a top class DM, we are linked to a few quality ones, and yet come the end of the transfer window we are low balling teams with offers to see if we can strike a bargain. Why risk that? Why not go in early, pay a premium if relevant and get the business done. If we believe the player to be that good than the premium paid will balance itself out.

Chelease really set the bench mark this season for transfer business, if Wenger has any common sense left in him he should use what they did as the bench mark.

Wenger is becoming a parody of himself. I loved we won the FA cup last year, however unless he starts balancing the team and not putting square pegs in round circles, i think he should go.
