Despite Manchester City's record-breaking campaign last season which saw them capture the league title with a century of points, Liverpool got the better of City in three out of the four games they played across all competitions.
With Sergio Aguero substituted, the Brazil global striker was ready to take the 86th-minute spot kick, but the City boss instructed Benjamin Mendy to tell Riyad Mahrez to take it instead.
Guardiola said that he had been impressed by Mahrez's penalty-taking in training.
The 21-year-old said: 'Obviously I'm not happy.
'However, it was important that we didn't lose.
"I would like to have taken it, I was confident, so I was not happy that they did not allow me".
Jesus was clearly disappointed (even if he felt a touch of "I told you so" afterwards) and he engaged in a conversation with Pep Guardiola at full-time.
"This is part of football, sometimes these things happen".
Arsenal and Tottenham Hotspur sit just two points behind the leading pack, too, and Robertson expects the race to involve several teams throughout the campaign. "I will support Riyad if the manager chooses him again", he said.
Liverpool have faced Spurs, Chelsea and City in three of their past four league games, winning one and drawing two.
As for the impact of Sunday's draw on the title race, the Netherlands captain said: "I think it is not about these games, it is all about the other games, the hard games we have against mid-table and lower teams". Unlike last season, Klopp could not call on Alex Oxlade-Chamberlain to penetrate City with runs from midfield due to the former Arsenal player's long-term knee injury lay-off. It showed we can do both - have the ball and be very strong as well. It was with the penalty but we had good chances as well.
