Manchester City are now hot favourites to win a fifth Premier League title in six seasons after Arsenal's 2-2 draw at West Ham on Sunday.
The Gunners threw away a two-goal lead at the London Stadium after goals from Gabriel Jesus and Martin Odegaard looked to have set them on course for a comfortable three points.
Said Benrahma scored from the spot for David Moyes' side before Bukayo Saka missed his penalty at the other end minutes before Jarrod Bowen's equaliser.
City had closed the gap on Mikel Arteta's side to four points with a commanding 3-1 win over Leicester City on Saturday. And with West Ham to thank, the Blues have been slashed to just 5/2 for the title, according to the latest offs from Betfair.
