The 1-0 triumph saw City usurp Arsenal as Premier League leaders.
With an FA Cup semifinal against Southampton on Saturday, Guardiola remarked afterwards: “Now we have to think about it a lot because I had a lot of doubts about the line-up today because of the fatigue on Sunday.
“In previous weeks we didn’t have a lot of fatigue as it was only a game a week. Now it will be three in a row in three days, go to London.
“I know that if we win it will be a good decision and if we lose it will be a bad decision.”
Asked about the sort of changes, he added: “I don’t know what I’m going to do. We will think. We need players with rhythm and ones who haven’t played.
We will see. I have two nights to sleep and we will see.”
