Chelsea manager Jose Mourinho is reportedly facing a battle to keep striker Romelu Lukaku at the club next season.
Lukaku spent the last campaign on loan at West Bromwich Albion and is thought to be keen to leave Stamford Bridge again on a temporary deal this summer.
Mourinho, who returned to Chelsea for a second spell on Monday, could soon be without the services of the Belgian, according to The Guardian.
Lukaku scored 17 goals in all competitions for West Brom during his loan spell at The Hawthorns.
