Gabriel's second-half header earned Arsenal a crucial 1-0 win at Tottenham Hotspur in a feisty north London derby on Sunday to keep pace with early Premier League leaders Manchester City.
Spurs started sharper, and David Raya was forced into early saves before Arsenal fought their way into the contest, although Jurrien Timber was perhaps fortunate to avoid a straight red card for a reckless challenge on Pedro Porro in the first half.
