City have won five and drawn one of their first six league games this season - but today's game is undoubtedly the biggest test of Guardiola's new-look side. "The City forward was in Holland on his day off and has sustained injuries".
It's not been a good 24 hours for Pep and City! "The first impression we have is that he has a broken rib, but exactly how many days he'll be off, I don't know".
But Guardiola insisted yesterday that he is not concerned by his players' off-field activities.
Before the injury, Mendy's ability to attack at pace along the flank, coupled with a unsafe delivery, had made City a more potent proposition than last term.
The France worldwide, who suffered the setback in the 5-0 win over Crystal Palace last Saturday, flew to Barcelona earlier this week for expert assessment, which revealed significant damage to his ACL.
Mendy, a 23-year-old left-back signed for £52 million, damaged his cruciate ligament on his right knee when playing for the Citizens against Crystal Palace at Etihad Stadium on Saturday (23/09/2017). City's midweek match against Shakhtar Donetsk saw Fabian Delph fill in Mendy's position, and the only other suitable option ahead of the club's weekend encounter with Chelsea comes in the form of natural right back Danilo.
The Spaniard was asked whether he would consider looking for a replacement left-back in January and replied: "We will see in January".
