Ironic that the biggest ever spending by a single club in a transfer window and all the big money moves in Spain came after the FFP coming into function. Goes to show how easily the big clubs manage to go around the system.
Huntelaar is a proper striker that Arsenal are in dire need right now. Welbeck operates much better on the wings rather than an out-and-out striker. I'd go for the Dutchman rather than Welbeck.
Kagawa will slot back into their first team. The void left by Gotze was one of the reason Bayern ran away with the Bundesliga last time. It'll definitely be a competitive title race this season at Germany. Fair play to Klopp.
The only think we can can hope is that him, Chalobah comes back as better players and improve especially on their defensive game and we can let Mikel leaves next summer.
