Jose Mourinho is overseeing a transition at Chelsea

Many players are leaving and arriving at the club this summer

The summer transfer window has already been busy for Chelsea and will continue to be so as Jose Mourinho looks to rebuild the club. Although the Blues have kept a constant string of trophies it is time for the Blues to change. Recent success has been built on the spine of Petr Cech, John Terry, Frank Lampard and Didier Drogba but with these players getting older and moving on the rebuilding job has begun.

Chelsea have already bought two players. The first arrival was Andre Schurrle who came in for £18m; the German favours playing on the left but can also play behind the striker and on the right. However, the 22-year-old could struggle to gain a starting place immediately due to Chelsea's 'three amigos' Juan Mata, Eden Hazard and Oscar.

The second signing is Dutch midfielder Marco Van Ginkel; he is tipped to eventually replace Chelsea legend Frank Lampard. The early signings from Mourinho suggest he is looking long term to build a strong Chelsea squad.

However, Chelsea's other targets signal that Mourinho is also looking for instant success. The Blues are looking for a new striker, with Fernando Torres possible leaving despite scoring 23 goals last season. He impressed in the Europa League but only two league goals from 23 December 2012 and the end of the season mean that Mourinho is expected to look elsewhere. Napoli striker Edinson Cavani would almost guarantee goals for the club but his £54m buy-out clause is too high and only PSG will meet that figure.

Wayne Rooney is also on the list but it is entirely dependent on whether he decides to stay at Manchester United. Having already scored 156 goals in the Premier League if Chelsea can bring Rooney in, his goal scoring could be enough to close the gap on the Manchester clubs.

Then there are the two young talented Belgians that the Special One has already made his mind up upon. Lukaku is set to remain at the Bridge and it could be him that ends Torres' and Demba Ba's Chelsea careers if he is joined by a big money arrival. After an impressive 17 goals in the league last season with West Brom, Lukaku could prove pivotal to next season. Mourinho has made a wise decision to keep goalkeeper Thibaut Courtouis on loan at Atletico Madrid next season as he gains both first team football and European experience.

With players coming in to Stamford Bridge there are also several players on the move. Having already released Florent Malouda, Hilario, Ross Turnbull, Paulo Ferreira and Yossi Benayoun, Chelsea are trimming the squad. Other players reported to leave the club are Marko Marin, John Obi Mikel and Ba. Mourinho's brutal way of cutting down the squad could prevail come May 2014 when trophies are decided.

All of the transfer talk circulating Chelsea shows that the new boss has a clear plan and he desperately wants to bring the league title back to Stamford Bridge. With a host of players coming in and out of the Bridge, Chelsea appear to be finally completing the transitional period that has been overdue.
