Manchester City midfielder Ilkay Gundogan says their 5-0 win at Cardiff City was significant in the team's development.

City recovered from a midweek Champions League defeat to Lyon to blast five past the Bluebirds, with Sergio Aguero, Bernardo Silva, Gundogan and substitute Riyad Mahrez (two) on target.

And Germany midfielder Gundogan, who scored the pick of the bunch just before half time, reflected: "It was very important - the game was tough today because of two reasons - we lost in midweek in the Champions League and it's always important to react.

"And the second one, Cardiff is a very physical team and even though we don't have the tallest players in our squad, it was about mentality, being in the duels and we were able to do that in a very good way and that's why we deserved to win."
