Guardiola covered Sunday's game against Premier League leaders Leicester after last night's EFL Cup win against Bournemouth.
The Manchester City boss delivered some fairly grim news as well as he considers what team to pick.
"We have 13 (first-team) players available for Sunday," said Guardiola.
"The sentence I love is 'it is what it is'.
"I would prefer to have more situations but I like to convince these players and this club, excuses don't exist – we have 13 players and have to win the game."
