"His injury is not easy, meniscus external, and it's not easy", Guardiola said.
Asked why Mendy is in Hong Kong, Guardiola said: "He's in Barcelona".
But he later uploaded a video in a vehicle with the location set as Hong Kong International Airport, something which prompted Guardiola to swear on live television after he was questioned about Mendy's whereabouts in a pre-match press conference.
"I have to install Instagram on my account to control my players because I don't know, really I don't know". 'He needs to re-adapt.
"Yesterday he was in Barcelona!"
"Wow, I didn't know". Before he said he was going one day to Paris, but Hong Kong is far away.

"I had tickets to go but the Premier League chose to put the game at Everton then".
A shock to Guardiola who thought he was in Paris.
They also have a new striker, Gonzalo Higuain, who scored his first Premier League goals in a 5-0 win over Huddersfield last week.
