Chelsea’s summer transfer window – How Mourinho can improve his squad including the arrival of Diego Costa

The Blues will be aiming to shake things up this summer.

It was a solid if unremarkable return to Chelsea for manager Jose Mourinho in 2013/14 and the club finished without silverware for the first time under the 51-year-old.

However, a third place finish in the Premier League and reaching the Champions League semi-finals can hardly be considered a disaster either, although things certainly need to be improved.

With the financial backing of Russian billionaire owner Roman Abramovich every transfer window is potentially a busy one for the Blues and Mourinho will certainly be looking to shake up his squad before the next season starts.

Here is how the Portuguese coach might do it.

Goalkeeper

Mourinho has a big decision to make this year, as despite the fact Petr Cech can still play for a few more years there is a young pretender on the horizon.

Thibaut Courtois is on the books at Stamford Bridge and yet has spent the past three years on-loan with Atletico Madrid – where his stock has risen so much that the Belgium international is recognised as one of the best ‘keepers in the world.

Cech meanwhile, despite having more Premier League clean-sheets than anyone else in history, has seen his form drop in recent times and a change between the sticks is looking increasingly likely.
