The Germany international has stated that loan side Sevilla are eager to keep in Spain, but that the Blues want him to return to Stamford Bridge.
The sheer number of exciting loan players heading back to Chelsea this summer is set to be a real boost for the Stamford Bridge side, with the likes of Romelu Lukaku, Thibaut Courtois and Lucas Piazon potentially ready to fight for a first-team spot next term.
Another player of real potential that’s future must be decided is Marko Marin, who has spent this season out on loan at La Liga team Sevilla.
The German has not been given a fair crack of the whip in west London, with extreme competition for places in the attacking midfield berths.
However, Marin has revealed that he has options ahead of next season and that both his parent and loan clubs are sounding him out about his future.
"Sevilla would like me to stay here, but in England they say they would like me to go back to Chelsea," the ex-Werder Bremen man told Deutsche Presseagentur.
"Until now nothing has been decided. We will discuss it at the end of the season."
Marin would do well to herald the example of Kevin De Bruyne; another exciting, international-standard winger who became frozen out at Stamford Bridge.
With the German starting to make an impact in Spain, he will surely be tempted by the opportunity to make his switch to the Estadio Ramon Sanchez Pizjuan permanent.
However, if Jose Mourinho does consider Marin as part of his plans it will give the playmaker a serious decision to make.
Marin has struggled with injuries since signing for the Blues and the opportunity to prove himself in England would also be a real motivation.
