The midfielder was full of praise for team-mate, who was in the thick of the action keeping Sporting CP at bay in the Europa League
Koke said he would give Jan Oblak a blank cheque to ensure he remains at Atletico Madrid after lauding the goalkeeper's performance in the Europa League.
La Liga outfit Atletico reached the semi-finals 2-1 on aggregate, despite Thursday's 1-0 loss at Sporting CP in Lisbon.
Oblak was in the thick of the action, producing a world-class save to stop Sebastian Coates and denied Bryan Ruiz twice, though he was at fault for Fredy Montero's winner.
