The tireless No.9 scored the only goal of the game not long into the second half, creating a shot out of nothing to secure three points for the Premier League champions.
The Etihad Player of the Month for August has continued his fine form through September and Guardiola couldn’t be happier with his player.
“If one person, one player deserves the best, it is Gabriel,” said Pep.
“He runs for everyone and when he scores, I am the happiest man.
“He can play in the three positions upfront and he does it really well.”
Jesus was on the end of a number of enthusiastic challenges throughout the 90 minutes, but never lost his cool or made a fuss to the referee.
It is that attitude that continues to impress his manager.
“We know from the past in the duels how aggressive they are, but you have to handle it at this level,” said Pep.
“Gabriel goes down, gets up and tries again. He’s a young player and one of the best signings we have done in this period together.”
Pep added Rodrigo was “exceptional. He was in the right position and he is growing as a player. Really good.”
And after setting a new win record as a City manager, the Catalan was keen to share out the plaudits with his staff and players.
“I am so proud,” said Pep.
“But in 221 victories, I never scored one goal. I will not be a good striker for the next few years.
“I share it for all the people in the Club and the players. All the years we spent together since day one,
“I cannot deny how proud we are to achieve that. To be close to Les McDowall the previous manager to do this is fantastic.
“To do it here at the home of the Champions League winners, and the way we played.
“We played with courage. We play every single game with courage, even in defeats.
“Sometimes I make bad decisions, but the players always respond, the way they play makes me so proud and it's why we have that record.”
