Ex-Arsenal defender Sol Campbell believes this season is the Gunners' "best chance" to win the Premier League title.
Arsenal have not won the league title since 2003-04 but can take a significant step towards their first league crown in over a decade - should they beat title-rivals Manchester City on Monday.
A victory over Manuel Pellegrini's men, combined with anything less than a win for leaders Leicester City, would see Arsenal top the pile on Christmas Day.
Campbell, who won two league titles with the club, is reluctant to make a prediction on the eventual winners with only 16 league games played, but feels his former club must capitalise on the season's unpredictability.
