The Blues, who are already said to be targeting Atletico trio Diego Costa, Felipe Luis and Tiago, are ready to challenge Barca for midfielder Koke according to Sky.

Barcelona want the 22-year-old as a replacement for Cesc Fabregas, who looks set to be on his way out of the Nou Camp this summer with Premier League duo Arsenal and Manchester United, as well as Chelsea, said to be interested.

But Jose Mourinho won’t let his old nemesis have it their own way, as he plans his own move for the Spain international, with Frank Lampard looking increasingly likely to depart Stamford Bridge.

However, despite the interest from the European heavyweights, Koke insists he is only focused on Atletico at the moment.

‘I still haven’t had time to read what has come out. I am on holiday and I plan to disconnect,’ he said.
