Manchester City have threatened to walk away from negotiations with Brighton for left back Marc Cucurella until next summer.
The reigning Premier League champions previously made a £30million bid for the Spaniard and the Seagulls rejected it as they value him at £50m.
City deem that valuation to be too high even though Cucurella is keen on the move. Meanwhile, Brighton have offered the player an improved contract to stay at the club.

City's alternative targets at left back include Benfica's Alex Grimaldo and Stuttgart's Borna Sosa.
