Gary Neville has slammed defender for his ‘really poor’ error which led to ’s goal in a 1-0 defeat for the Blues.
Julian Alvarez scored the only goal of the game after just 12 minutes at the Etihad as City’s title celebrations got underway on Sunday.
Alvarez pulled away from his marker and slotted home after Cole Palmer picked him out with an inch-perfect through ball.
But the attacking move started when Chelsea’s Fofana gifted possession straight to Kalvin Phillips, who passed to Palmer to provide the assist for Alvarez.
‘Really poor give away from Fofana,’ Neville said during commentary of the match on Sky Sports.
‘It is never in doubt from Palmer, it is so accurate and precise with his pass, brilliant when Alvarez is one-on-one with the goalkeeper.
‘City may have made more changes, but they have started much better than Chelsea.’
Fofana was one of many players who arrived at Chelsea this season with the centre-back signed in a deal worth £75m from Leicester City.
The 22-year-old Frenchman had made 18 appearances for the Blues, in what has been a horrific campaign for the west Londoners.
Their poor season comes despite the club spending over £600m on players since co-owner Todd Boehly took over from Roman Abramovich.
