- Pep Guardiola showed displeasure on Benjamin Mendy's performance down the touchline
- Reece James gave the French defender a workout in Chelsea's win over Man City at the Etihad
- Both teams will lock horns again in this season's Champions League final
One of his concerns was stopping Blues defender Reece James who on a few occasions went past Benjamin Mendy at left-back.
The Spanish boss rested a couple of players to keep them strong for the all-important Champions League final against Thomas Tuchel's men.
And despite not playing with his full squad, the Citizens dominated most parts of possession and took the lead through Raheem Sterling.
But Chelsea pressed high and James was one of the players causing problems for City's defence down the left.
There was an instance the England defender glided past Frenchman Benjamin Mendy with ease right in the front of Guardiola as the Spanish boss went to the ground down on the touchline holding his head.
Hakim Ziyech responded three minutes after the hour mark to make it 1-1. And with ten minutes left to play, Pep subbed Mendy for Oleksandr Zinchenko.
But that did not stop Chelsea from grabbing the winner through Marcos Alonso in the 92nd minute to give the Blues an emphatic 2-1 win.
City were also knocked out of the FA Cup semi finals by Chelsea and Guardiola knows his team have to wake up not to fall victim again to the west London club in the Champions League finals.
