Kevin De Bruyne believes the mental and physical toll of chasing the quadruple could make the feat nearly impossible for Manchester City.
City moved a step closer to an unprecedented clean sweep of four trophies by reaching the FA Cup final with a narrow 1-0 victory over Brighton at Wembley on Saturday.
Yet manager Pep Guardiola described the quad challenge as almost impossible after the game and De Bruyne agrees that the congested fixture list presents a tough obstacle.
