Chelsea manager Jose Mourinho is preparing for a summer overhaul at Stamford Bridge, which could include the additions of Real Madrid stars Raphael Varane and Fabio Coentrao.

On his second stint at Chelsea, and following a first season without silverware, the Portuguese boss rebuilt his squad in summer 2014 with the additions of Diego Costa, Loic Remy, Didier Drogba, Cesc Fabregas and Filipe Luis, with Frank Lampard, Fernando Torres, Samuel Eto'o and Demba Ba moving in the opposite direction.

And despite the Blues winning the Premier League and League Cup this season, The Telegraph suggests Mourinho is ready to make changes once he commits his own future to the club with a new contract.

With Petr Cech, Luis and Drogba expected to leave the club, the Chelsea manager will be looking to replace them and also add more depth to the current squad in order to challenge for the Champions League.

Mourinho has been said to be in the market for a long-term replacement to John Terry and is also considering the signing of a versatile forward as well a midfielder to back up Cesc Fabregas and Nemanja Matic.

The Telegraph claims Coentrao and Varane are on a long list of targets that also includes Barcelona wantaway Pedro Rodriguez and Atletico Madrid duo Koke and Antoine Griezmann.

Mourinho signed Coentrao from Benfica during his time as manager at the Santiago Bernabeu and could be open to reunite with him at Stamford Bridge to back up Cesar Azpilicueta should Luis decide to return to Atletico Madrid.

Meanwhile, the boss has never hidden his admiration for Varane, although it is unlikely Real Madrid will want to negotiate his departure.

And while there is the possibility of Chelsea cashing in with Oscar, the Blues are monitoring Paul Pogba, Gareth Bale and Raheem Sterling should they decided to make marquee additions in the summer.
