Chelsea are put behind after an 18th minute goal from Gundogan put Guardiola’s men in front.
Frank Lampard is currently under pressure to produce results as it looks likely he could record another loss.
Mendy was far from stopping that as Chelsea’s defense was weak to stop the strike.
See goal below.
Phil Foden added another number to the goal as Mendy looks dull to stop a goal today.
