Hart not taking Man City place for granted
Hart has been criticised over his decision-making for City, who are currently 12 points adrift of rivals United.
Hart, who has let in just 24 league goals, admitted: "It's hard to be No1 at a club like this now - any dip in the form and that won't be the case.
"I have got to keep some high standards and ride through the low times and try and have as many good ones as possible. But it is a big thing for me when you are standing alongside some of the greatest players in England, and it feels good and exciting."
