As has become custom, City supporters also booed the Champions League anthem before kick-off in continuing protest at organiser UEFA, with whom they have various issues.
Speaking on ITV following Man City’s impressive 4-0 performance against Borussia Moenchengladbach, Keane hailed the new Spanish manager’s influence so soon at the Etihad.
City hardly seemed inconvenienced by the 24-hour postponement of the fixture after a torrential thunderstorm on Tuesday.
Guardiola wants the City supporters to forget the past and embrace the competition as he tries to build a team which can compete on a regular basis with the heavyweights of Europe.
“Our fans they have know we play for them”, he said.
“Only what we can do is play every time better than before so people say, “wow, I spent 90 minutes there and I had fun”.
“He has to know that behind him there is a team that is going to help him if he is going to help us. He is going to be an important player for us”. Coming here in three or four weeks are the best football player ever with Luis Suarez and Neymar and all of the fantastic team at Barcelona and they have to come here to enjoy it.
The Spaniard has started his reign at the Etihad Stadium in fine fashion with seven straight wins in all competitions thus far.
“With what these players have done since the beginning – in our games home and away – our players deserve the standing ovation”.
“Hopefully against Barcelona and Celtic it will happen and if you are able to go to the next stage”.
“I’m really happy. I’m so happy”. If we didn’t get points in the first game at home against Gladbach, it would make games against Barcelona and Celtic more hard.
“Today the stadium was not completely full so the only thing we can do is play good”.
“I know perfectly Borussia”.
“If he continues to help us in that way he is going to score a lot of goals, like Keli [Iheanacho], like all our strikers”.
However, as long as Aguero continues to contribute to his team’s relentless aggression without the ball, Guardiola believes the goals will take care of themselves.
“It was hard for them to control our build-up because of our movement between each other”.
Keane’s comments come after one of Manchester United’s greatest icons, Sir Alex Ferguson, sought out the City boss after he’d inflicted derby defeat at Old Trafford and gave him a hug.
