The Brazilian limped off the pitch in the first half and could be out for some crucial games.

Arsenal have finally ended their Goodison Park hoodoo in their final Premier League trip to Everton's iconic stadium — the Toffees will move to their new ground next season — by beating Sean Dyche's men 1-0 on Sunday.

Prior to this weekend trip, the Gunners had not beaten the Merseyside club away from home in the English top flight since October 2017 but Leandro Trossard's brilliant goal was enough to end this horrible run.

Unfortunately, this game came at a cost. Gabriel Martinelli, one of Arteta's best attackers, picked up an injury early on in the game and was forced to limp off the pitch after scoring a lovely goal which was later overturned by VAR — Eddie Nketiah was deemed to be offside in the build-up.

The Brazilian went straight down the tunnel but later re-emerged and joined his teammates on the bench, hinting that it was not serious. However, the manager offered an update after the final whistle and Arsenal fans will not have liked the news.

As revealed by the Spaniard, Martinelli suffered a hamstring issue and while the extent of that injury remains unknown, this looks set to rule him out for two crucial games.

The first is Arsenal's midweek clash at home to PSV, the North London giants' first UEFA Champions League game in seven years. While the Dutch side are flying high in the Eredivisie this season, Arteta's men should be able to cope without the Brazilian.

The bigger concern is next weekend's clash with Tottenham in the Premier League, as Arsenal host Spurs in the first North London derby of the campaign. While the Gunners boast a fantastic home record in this tie, Maddison and Co. have been soaring under Ange Postecoglou and will fancy their odds of getting their first Premier League win at the Emirates Stadium since November 2011 — and only their second victory there overall.

Martinelli's hamstring issue could heal over a few days if it is a low-grade issue. However, two to six weeks could also be the outcome. The club will be hoping there is no tendon issue as that could rule out the 22-year-old for up to three months.
