The 21-year-old has attracted lot of interest from other clubs but Chelsea manager, Jose Mourinho wants the Belgian to get more exposure before he becomes a regular starter at Stamford Bridge.
Lukaku has performed extremely well for his country in the ongoing 2014 FIFA World Cup as he was clinical against Belgium’s match against USA as he not only set one for Kevin DeBryne but also scored a goal to help Belgium book a ticket to quarter-finals.
Lukaku has been seen as a potential talent and the Chelsea forward for the past two seasons has been on loan to Everton and West Brom.
Besides Lukaku, the Spanish outfit are also planning to lure Goalkeeper Thibaut Courtois on a loan deal for the fourth consecutive season as well as forward Demba Ba.
Having already bought striker Diego Costa, Jose Mourinho is planning to land Croatian striker Mario Mandzukic, thus opening up loan moves for both Lukaku and Ba.
