City have been in stunning form since the start of the season, but Hazard believes beating Atletico - Champions League finalists in two of the past four seasons - shows Chelsea can compete with anyone.
Hazard has always been linked with a move to Real Madrid and Gerrard explained why performances like last night will invite them to hound Chelsea - just as Barcelona did with Philippe Coutinho this summer.

"Man City will have great confidence and it will not be easy but my team has prepared well in limited time", Conte said in his presser on Friday.

'Honestly I am not anxious because I have players who try to make the best decision.
