Real Madrid coach Jose Mourinho has opened the door to returning to Chelsea or Inter Milan.

Mourinho is under pressure in Spain despite reaching the Champions League quarter-finals.

"I have an adventurous spirit and do not know what will happen next season," declared The Special One at the opening of an exhibition in Setubal.

"It's not easy to choose a new destination after working in England, Portugal, Italy and Spain. Maybe I could return to somewhere I've already been. Watch out for surprises."
