Former Chelsea manager Carlo Ancelotti has tipped Arsenal to win the Premier League title this season.
The Gunners edged out Everton 2-1 on Saturday to move top of the table, before Manchester City won the point needed at Manchester United to usurp them at the summit on goal difference yesterday.
Although Ancelotti - who won the competition with the Blues in 2010 - feels that City's squad is unparalleled, the Italian believes that Arsene Wenger's nous could see them go all the way.
"Manchester City are the most complete squad in the Premier League, but every now and then they go off piste. They are not 100% reliable," he told La Gazzetta dello Sport.
"I'd watch out for Arsenal. Arsene Wenger did well to change their system, so he waits and counters to get the best out of the pace of Theo Walcott and Alexis Sanchez."
The Sky Blues and Arsenal sit 11 points clear of reigning champions Chelsea in 15th.
