Chelsea FC are the clear winners, not only in the top four but in the whole Premier League as well. First time in his managerial career, Jose Mourinho made a lot of money by selling his players. Their net spend was only £7.8 Million, which is the least figure among top 4 teams. This net spend rate is even less than Burnley and Hull City. Jose Mourinho sold David Luiz for £50 Million which is considered as finest piece of business by the Special One.
Arsenal started this transfer window in an impressive way by signing Alexis Sanchez from Barcelona. Wenger managed to get Sanchez from the jaws of Liverpool. Calum Chambers and Mathieu Debuchy were added to the squad and it looked like a successful start. But as time passed by, frustration started to grow in Arsenal ranks. Their inability to sign a strong central midfielder was criticised throughout the transfer window. And with the sale of Thomas Vermaelen, other loop holes were clear in Arsenal squad.
