Cesc jumping ship?

Cesc was recently photographed wearing the new Puma Powercat boots...when players start to experiment with other boots it usually means that their contract has expired or they are in negotiations. It would be a big downfall for Nike to loose Cesc to Puma considering that Cesc is one of the faces of the CTR360 which is Nike's control boot. Only time will tell but this would be a big pickup for puma.
