Pep Guardiola believes Manchester City have it all to do if they are to overhaul leaders Arsenal at the top of the Premier League table.
Reigning champions City can move back to within five points of the Gunners away to Chelsea on Thursday after Arsenal dropped points in Tuesday's goalless draw with Newcastle.
"We have to be almost perfect and hope they drop points. Last night they were still excellent."
Chelsea have won just one of their last seven Premier League games but Guardiola still expects a difficult encounter at Stamford Bridge. "They're all tough. They're a tough side, well-managed. It doesn't matter what position you are when you go to Stamford Bridge. It is always difficult."
