Arsenal stormed back on Monday to extend their Premier League lead to seven points, coming from a goal down to defeat a resilient West Ham United side 3-1 as their victory marked the resumption of the top-flight season and saw them continue their reign as log leaders.

Bukayo Saka equalized from close range in the 53rd minute and Gabriel Martinelli smashed home a shot six minutes later to put Arsenal in front.
Eddie Nketiah scored Arsenal's third to complete the victory and ensure they maintained their 100% home record. They have 40 points from 15 games, seven clear of Newcastle who have played a game more. Arsenal are eight ahead of third-placed Manchester City, who have played 14.
"We showed a lot of composure and quality," said Arsenal manager Mikel Arteta. "We didn't start to play the game they wanted to play. We kept pushing, believing and deserved the win."
Joelinton, Miguel Almiron and Chris Wood were all on target as a ruthless Newcastle struck three times in the first half against Leicester to fuel their fans' dreams of qualifying for the Champions League, or perhaps more.

Fourth-placed Tottenham got off to a nightmare start at Brentford, but yet again staged a comeback with Kane and Pierre-Emile Hojbjerg scoring in a space of six minutes in the second half to cancel out earlier strikes from Vitaly Janelt and Ivan Toney.
