The 19-year-old’s sending off somewhat soured a great display in City’s 5-1 win as he earned a second yellow card late on for pulling back Martin de Roon.
Guardiola protested the decision with the fourth official at the end of the game but said afterwards that the young City midfielder should see it as part of his education.
“He will learn,” Pep said.
“He will know after one yellow card he has to be a little bit more careful for the second.
“People say he has to play more minutes and I want to let him. But there are things he is still far away from compared to David Silva and Kevin De Bruyne.
“He has to learn these situations, with a yellow card, be careful. The word ‘experience’ – it means that.
“He is not going to get fined. I only fine players for stupid things, not for cards that are part of the game. Maybe I have to pay him for how well he played!”
Of his heated discussion with the fourth official, Guardiola added: “He asked me not to say any more otherwise I would get a yellow card and they have the power!”
It was otherwise a good night for City with Raheem Sterling netting a hat-trick as City came from behind to maintain their 100 per cent record in the Champions League.
Sterling thought his side had displayed the sort of ruthlessness Guardiola expects.

“I thought we were clinical today. It was a difficult game but we stayed patient, created chances and took them,” Sterling said, later tweeting ‘perfect night’ about his first Champions League hat-trick.
Pep was also obviously unhappy that John Stones wasn’t ready to replace Rodri – who limped off with a hamstring injury in the first half.
Stones later explained the delay: “I had them (shin pads) on, I just needed to fix them up properly. Time was of the essence and that is what the manager wanted.”
