Chelsea manager Jose Mourinho is reportedly plotting a mini overhaul to strengthen his team further despite winning the Premier League title with three games to spare.

According to the Mirror, the Blues hierarchy are ready to back the manager in his pursuit, but first want the Portuguese manager to sign a new contract with the club.

The Stamford Bridge outfit are keen to continue their association with the former Real Madrid manager and have offered him a two-year extension on his £12m-a-year contract keeping him at the club until the summer of 2019.

The report claims that Mourinho is targeting a midfielder, a forward, a defender and a goalkeeper during the summer transfer window and owner Roman Abramovic is ready to back his manager to land the players he desires.

Atletico Madrid winger Antoine Griezmann, Lyon striker Alexandre Lacazette, Read defender Rafael Varane and Getafe keeper Vicente Guaita are reportedly on top of the manager's wish list for the summer.

The former Real Sociedad player, who only moved to the Spanish capital club in the summer, has been prolific in the La Liga and it is believed that he has a £43m release clause, which the Blues are ready to match.

Mourinho has already hinted that he will sign a striker in the summer, as they were left short in that department during parts of the season. And it is Ligue 1 top scorer Lacazette, who is the manager's first preference to challenge Diego Costa for a starting role.

With John Terry getting on in age, the former Inter Milan manager has identified Varane as the perfect long-term replacement for the Blues skipper and is keen to reunite with his former charge.

And finally, a goalkeeper to replace the outgoing Petr Cech, who has confirmed that he, is not keen to spend another season on the bench, and the Chelsea manager has identified Guaita as possible backup for current number one Thibaut Courtois.
