Roman Abramovich has been told by Jose Mourinho that he must sign German midfielder Sami Khedira in the summer if he wants to convince the Real Madrid boss to return to Chelsea.
There has been plenty of speculation that Mourinho will return to Chelsea in the summer, with current interim manager Rafa Benitez making it clear that he will leave the club at the end of the season.
Mourinho has stated that he would consider a return to one of his former clubs when he leaves Real Madrid and the general consensus is that a move back to west London would be the most likely scenario.
Abramovich may have had a strained relationship with the Portuguese manager towards the end of his spell in charge but it seems Mourinho is now going to test his resolve by making numerous demands over his return.
German newspaper Bild is claiming that Mourinho has already demanded that Chelsea sign Khedira who has been a crucial part of Madrid's success in recent seasons.
The German international has been an integral member of the first team under Mourinho and helped the club win the La Liga title last season, while he has been equally influential in helping Madrid reach the semi-finals of the Champions League this year.
Madrid would certainly not want to lose one of their most important players, but it seems Mourinho wants Chelsea to flex their financial muscle to prove they can once again become title challengers.
When Mourinho first arrived at Chelsea back in 2004 he quickly made a host of big-money signings that helped him secure two Premier League titles during his three and a half year reign.
The Blues are desperate to bring success back to the club and it seems Abramovich may well have to put his personal differences aside in order to convince the proclaimed 'Special One' to come back to Stamford Bridge.
Khedira would certainly be a strong acquisition for Chelsea, with the 26-year-old having won the league title in Germany and Spain, while also becoming one of the most important members of the national team under Joachim Loew.
