Manchester United and Chelsea were tipped to battle it out for the 22-year-old midfeilder, but now it seems both sides will have to look elsewhere as Koke commits his immediate future to Atletico Madrid.
Speaking to reporters, Koke said: "My future is with Atletico. I am happy in my club and now I have a deal and do not think about an exit."
Koke is a product of the youth academy at Atletico Madrid having signed for the club when he was eight-years-old. He has gone on to be a staple in Diego Simeone's remarkable side that won La Liga last season and reached the Champions League final.
The successes of Atletico Madrid means the club are faced with a tough summer keeping hold of their star players, as the rest of Europe's elite lick their lips at the prospect of dismantling Simeone's team.
Diego Costa has already completed a medical ahead of a move to Chelsea, and Mourinho is reported to be keen on also bringing Tiago back to Stamford Bridge alongside defender Filipe Luis.
Atletico Madrid president Enrique Cerezo has acted quickly to dispel any talk of the club selling all of it's best players, Cerezo said: "We are not a selling club. We are a stable club. And I insist: Koke wants to play for Atletico, he is our franchise player and will continue a Rojiblanco. There's nothing else to add."
However many would argue that in recent history Atletico Madrid are a selling club, in fact the Spanish side seem to be a factory capable of churning out world-class centre forwards to be then sold on at a high price.
Sergio Aguero fetched €45m from Manchester City whilst his replacement Radamel Falcao was auctioned off to Monaco for €60m last summer. In 2007 Fernando Torres was sold to Liverpool for close to €25m.
But with success finally achieved at Vicente Calderon, it seems times are changing at Madrid. Costa may be heading for the exit doors, but Koke is setting an example for the rest of his team-mates and is going nowhere.
