Real Madrid are willing to bid £15 million for Chelsea defender Branislav Ivanovic.

Ivanovic joined Chelsea from Lokomotiv Moscow in 2008 in a reported €12 million (£9m) deal.

"I know what has been written about my future and that Madrid are following me, but now is not the time to talk about this," the 28-year-old told Marca.

"I am focused on the national team now and I am very happy at Chelsea."
