An Erling Haaland penalty and Manuel Akanji header either side of Thiago Silva and Raheem Sterling goals saw the sides go into half-time level.
We took the lead shortly after the restart through Haaland before Nicolas Jackson responded for the hosts.
A deflected Rodrigo strike in the 86th minute looked to have given us the win before Cole Palmer scored an added time penalty to round out a Premier League classic.
Guardiola took a philosophical view of events in his post-match press conference, believing the result could have gone either way.
“Could be better, but could be worse too, so it’s good for the Premier League,” he said.
“They started better, they are trying to build something here with a lot of new players.
“It was a tight game, we had our moments when it was 2-3 in our transitions – not to kill the game, because with 40 minutes left, many things can happen.
“We had moments and our goal at 3-4 – we were lucky, and we didn’t make perfect decisions, but the quality they have, it is what it is.
“Right now, it was a fair result – both teams played to win.
“Many things were going to happen, but of course, we are ahead going into added time, we could defend better, and the penalty is a penalty. We created a lot of chances – the most in my visits to Stamford Bridge, but they created a lot, too.”
Guardiola said on Friday that he expects mid-table Chelsea to challenge for trophies again soon and he reiterated that belief after seeing Mauricio Pochettino’s side up close today.
“I had an opinion before, during and after about how good they are and nothing has changed,” he stated.
“Chelsea is Chelsea and they have been one of the best teams of the last 20 years so I couldn’t expect anything different.
“If you are saying it is a long time since we lost, that is a good sign - today, we didn’t lose so we go away with a good point having created a lot of chances. It was a fair result for both teams.”
