Antonio Conte admits Arsenal have the advantage in the race for the top four but warned Tottenham are ready to fight them all the way.
Spurs, who have had an inconsistent 2022, beat West Ham to secure successive Premier League wins for the first time since early December and move up to fifth.
A Kurt Zouma own goal and two Heung Min-Son strikes - all set up by Harry Kane - lifted Conte's side to within three points of their north London rivals Arsenal.
Arsenal also have a game in hand and a date for two sides' second league meeting of the season has yet to be confirmed.
