Chelsea are considering an approach in signing Real Madrid midfielder Sami Khedira in the summer, according to the Express.

The Blues manager Jose Mourinho signed the midfielder from Stuttgart in 2010, while the Portuguese tactician was in charge of the Spanish capital club.

The German international was the firm favourite for the former Real boss as he has been a key player in the nine-time European champions' midfield during his spell.

The report claims Mourinho is a big fan of Khedira and is weighing up a bid of £35m in signing the 27-year-old in the summer transfer window. The midfielder is yet to make a comeback to Real's first team after being sidelined with injury in November.

Khedira tore knee ligaments while on international duty late last year and is eyeing for a comeback to the first team. He has already started training with the Spanish giants and is keen on cementing his place again in Real's starting lineup.

Carlo Ancelotti has fielded former Tottenham Hotspur midfieder Luka Modric and Spain international Xabi Alonso in the midfield in Khedira's absence. The duo has impressed for Real and with their current form, the German midfielder could find it tough to break into the playing XI.

A move to Chelsea for Khedira could see him rejoin with Mourinho at Stamford Bridge. The addition of the former Bundesliga midfielder is likely to see him pair with Nemanja Matic in the midfield at the west London club.

Meanwhile, Chelsea have confirmed their stopper Petr Cech will be out of action for eight to 10 weeks after successfully undergoing a surgery.

The 31-year-old sustained a dislocated shoulder during Chelsea's first leg Champions League semi final clash against Atletico Madrid.

"Petr Cech successfully underwent surgery today (Wednesday) following his shoulder dislocation in the Champions League semi-final first leg against Atletico Madrid. He will be out for approximately eight to 10 weeks," ‎ a statement read on Chelsea's official website.
