Chelsea legend Gianfranco Zola has left the door open to a return.

Zola, who has not worked since leaving Upton Park in 2010, has been repeatedly linked with a return to Stamford Bridge in a management role.

In the last fortnight, he has visited training at Barcelona and Pescara to gain tips from Pep Guardiola and Zdenek Zeman.

"I am awaiting the right opportunity," he said. "But I am not sitting around doing nothing. I want to learn and challenge myself.

"For now I am enjoying myself playing golf and relaxing a lot. But the beautiful game still really attracts me.

"Let's speak again in the summer."
