Chelsea manager Jose Mourinho is reportedly eyeing up a fresh move for Atletico Madrid midfielder Koke.
Chelsea are thought to have named the Spanish midfielder as one of their key transfer targets, as boss Jose Mourinho looks to add more creativity to his squad this January.
However, Atletico are in rush to sell and they are playing hard ball about any possible deal.
But according to the Fichajes.net website Mourinho is ready to force them to do business by activating the mammoth clause.
However, they will have a battle on their hands as Manchester United and Manchester City are also keen on a deal.
