Manchester United ended City’s record-breaking 21-match winning run at the Etihad Stadium, in turn cutting the gap to 11 points at the top of the Premier League.
City can stretch that again when they face Southampton on Wednesday evening and their manager said he has witnessed the requisite hunger to finish the job.
‘I didn’t watch the game. We don’t have time. I watched many Southampton games,’ Guardiola said.
‘Maybe we’ll play United in the FA Cup but if we don’t then it will be next season.
‘We’re in the Champions League, they’re in the Europa League. We already played them in the Carabao Cup.
‘There was disappointment, sadness, then the second day it was better and today completely on fire to do a good game tomorrow.
‘It’s a normal process when you lose. The reaction is common. Everyone realised how difficult it is to go on a good run and we did it. The Premier League is so complicated, so difficult.
‘Sometimes it is good to live it [defeats] to realise what we have done. We are alive in all competitions and now we’ve arrived at the important part of the season.’
Guardiola still maintains that City can be caught in the title race, despite their rivals having to catch up with only 10 games remaining.
‘When the option is open, anything can happen,’ he added. ‘Nobody thought we’d do 21 games in a row so anything can happen. United can do it. We have to win six or seven games to be champions mathematically
‘We played really good against United apart from the first 10 minutes. I have an idea in general of the guys who will play tomorrow but I have a few doubts. Tomorrow I will decide.’
