He literally said "there's something wrong here" after the decision was given and that was at the refs'. For me the implication that City have bought the refs was introduced, or that the refs have made a terrible terrible mistake.
Lets imagine Aguero was commentating, he would have called that a penalty 50/50 but City deserved it because Haaland couldnt jump - The media and oppo fans would have called it out but City would get to have some say, some influence, in how things are seen.
But actually looking at it in the cold light of day it was a fifty penalty at worst. I think it was clearly a pen myself, the stuff before was handbags where the refs let it go.
