John Stones says Manchester City's battling spirit is a "sign of a great team".
City picked up their 20th successive victory across all competitions by beating West Ham 2-1 at Etihad Stadium on Saturday.
Pep Guardiola's men were made to work hard for the three points against a well organised Hammers outfit, and Stones was pleased with the mental toughness the squad showed to extend their unprecedented winning run.
