Pep Guardiola hailed match-winner Nathan Ake for knocking Arsenal out of this season's FA Cup.
Ake's 64th-minute goal gave Manchester City victory over Mike Arteta's Premier League leaders at the Etihad Stadium. City boss Guardiola hailed Ake and said: “What a season he's playing. He controlled one of the toughest opponents in the Premier League, because Bukayo Saka is in an incredible moment.
"He's an exceptional guy, there was a period where he didn’t play and he never complained once. Arsenal have taken a step forward. It was a tight game and you realise how good a side they are.
