Chelsea and Atletico Madrid are close to pulling off a £30m Koke deal, if The Express are to be believed, which would see the Spain midfielder join the Blues and Filipe Luis going the other way.
Koke is worth around the £44m mark, but reports say Mourinho is willing to offload Luis, who has failed to make an impression since moving from Atletico last year, as part of the deal.
The 23 year old Koke is a superb passer of the ball, which has caught the attention of Mourinho as he looks to strengthen the midfield for next season's title defence.
According to reports, talks between the clubs have already begun, with Chelsea top brass flying over to Spain to watch the playmaker in recent games.
What do you think Chelsea fans? He looks like he'd be a sterling addition to the squad, but is £30m too much? Let us know what you think in the comments below.
