Asked if Gundogan did not get enough credit for his performances, Guardiola said: "The important thing is the credit he has from all of us, he is an exceptional player. It was outstanding from Ilkay today." He added of Mahrez, who set up Gundogan's goal as well as scoring himself: "It's a pleasure to watch him play football."
