Manchester City boss Pep Guardiola was delighted with his players for their 3-2 win at Champions League opponents Schalke.
Raheem Sterling produced a 90th minute winner for the visitors in the first-leg of their round 16 tie.
Guardiola said: "It was a great result. We gave them two penalties, we gave them a red card and in this competition that is not too good. We are still not ready to fight for the later stages. but the result is good.
"We played good. But still we lost some easy balls which we are not allowed to do in this competition. Were they penalties? I think so, they are two penalties, I trust VAR. I have arguments sometimes but not this time. They are both penalties.
"We played with incredible personality. We gave two goals when they did absolutely nothing. It is not over, this competition is completely different."
