Chelsea boss Andre Villas-Boas says he's already an old-hand when it comes to job speculation.

Enduring a difficult time with results, Villas-Boas has also had to see rumours of his replacement as manager bandied around the media, yet he insists speculation does not affect him.

"It doesn't affect me at all. Last year [at Porto] I was linked to lots of different clubs, it is the same whenever results don't go, managers get linked with this club," he said. "Your strong favourite went to another club so now you choose another and at the moment it is that one."
