But there was still enough time for fellow youngster McAtee to be handed his top flight debut late on, testing Jordan Pickford with a vicious near-post drive as stoppage time approached.
Asked to assess both City youngsters’ performances, Guardiola insisted their senior opportunities are fully deserved.
He reflected: “I said many times, all of us we believe, not just me, Txiki (Begiristain) as well, we believe we have a good generation in the academy, with four or five players with quite good potential to help us.
“When we can use them, I am delighted. We don't give them opportunities just because they are in the academy, we believe in them and then it’s on them to show it.
“For our fans, I know how they like to see Phil and Cole and the next one to come. The rest is about being patient. Work hard and when they have opportunities, they have to play good.”
