The 32-year-old, who has just over a year remaining on his current contract, has endured a similar fate to that of fellow Blues stalwart Frank Lampard ever since the Spanish boss controversially succeeded Roberto Di Matteo earlier this season.

"But you have good competition here, you have good players. At this time Gary Cahill was doing really well, Branislav Ivanovic was doing well, David Luiz is doing well, too.
"So he has to accept, everyone has to accept, that we have a good squad and, when we have a good squad, you have to compete. It's part of the game if you're in a top side when you play so many games."
