Aaron Ramsey refuses to drop Arsenal's title hopes. Ramsey has a feeling it won't be as straightforward for Chelsea as it seemed a few weeks ago - especially if Arsenal maintain their current form.
"In the Premier League, strange things happen," he said. "Upsets happen - Manchester City went to Burnley and lost.
"We just have to focus on ourselves and believe other teams around us will be on the end of those upsets.
"And we've just got to be switched on and make sure it doesn't happen to us and maintain this run we're on."
