I had nearly two days off and going to the airport was when I had that accident.
The Argentine suffered the injury when the taxi he was travelling in veered off the road and collided with a post during a break in Amsterdam ahead of his worldwide commitments with Argentina.
"He did his first training session after what happened", Guardiola said.
"Hopefully as soon as possible he will be back".
"Maybe [he is in contention to play against Stoke]". We will see today.
"He is not 100 per cent but he is quite well". It was not as risky as it could be.
"Then one thinks 'why did I [go]', but it's hard to imagine that something like that could happen".
"We will see. We are happy he is back in training".
Midfielder Joe Allen will miss the match, after suffering concussion while on worldwide duty with Wales, while defenders Ryan Shawcross and Bruno Martins Indi are unlikely to feature due to respective back and groin complaints. "He's much, much better but he's still injured".
"Hopefully, it is the last part. He'll notice how he feels and when he'll be able". "Everyone has to be involved in everything and that is why everything is important even with the players who don't play, everyone is important".
He said: "The big problem we have is Mendy - six months out". It's a big problem. We're going to suffer in this situation, even though we have Fabian (Delph), Danilo, (Oleksandr) Zinchenko.
Guardiola was asked about the possibility of another move for Arsenal's Alexis Sanchez, but he said firmly: "The window is closed now". "Unfortunately it was long open, but now it is closed".
"We will see about January, we are in October".
"It is good to win the Premier League Manager of the Month but all credit to the ones on the pitch doing their job, the players". "It'll be a tough game".
