Pep Guardiola has admitted that Manchester City must learn from their 3-3 draw with Celtic.
Given the gulf between the Premier League and the SPL, City could have been forgiven for thinking they might have had a far easier evening in store.
However, Brendan Rodgers’ men surged into the lead three times thanks to a brace from Moussa Dembele and a Raheem Sterling own goal, City’s replies coming from Fernandinho, Sterling, and Nolito.
Up until this Champions League game, Guardiola had no experience of being behind as Sky Blues manager, so it will at least have been a learning curve for him.
“It was maybe a good lesson for us, how important it is to start well,” he told Sky Sports.
“It is not easy to recover one goal, imagine two, imagine three.
“It was mentally a shock at the start of each half, to concede a goal after two minutes. In the second half, aside from the first five or 10 minutes, we played well, we created chances.”
City’s leaky defence will need to improve ahead of a visit to White Hart Lane to face Tottenham on Sunday, with Spurs the only other unbeaten team in the top flight.
The Lilywhites did the double over the Etihad outfit last season, so Guardiola will be all too aware that his perfect start to this campaign is under threat.
