Chelsea‘s good run came to a halt on Saturday when they lost 1-0 to City at Stamford Bridge.
After Alvaro Morata came off with a hamstring problem, Conte brought on Willian instead, playing him up front.
“Their dominance of champions Chelsea, despite the narrow 1-0 scoreline, was a huge statement by City,” Shearer told The Sun.
“It was also worrying for Chelsea that they could be dominated so much on their own turf.
“He had just scored a midweek winner against Atletico Madrid and his confidence must have been soaring.”
