1. Marco Reus – Borussia Dortmund to Arsenal
Though Arsenal have only just spent £42.5m on Mesut Ozil, reports recently have suggested that Arsene Wenger is still keen to bring Reus to the club in the new year.
Reus has a £35m release clause installed into his current deal and should they decide to press ahead with a move there would be very little that Dortmund could do to stop him from going.
Dortmund are currently haemorrhaging talent, with Gotze having already left they are also set to lose influential striker Robert Lewandowski, and now they are fearful that Reus could follow suit.
