The London giants have thus ended a two-match winless streak in the championship and have three points more, but also a game more than their closest follower and only title contender, Manchester City, who played the FA Cup semi-finals almost at the same time. On the other hand, the "Magpies" suffered their fifth consecutive defeat in all competitions and remain 14th in the table with 42 points.
The decisive moment came in the ninth minute. Noni Madueke took a corner kick, Kai Havertz laid the ball off to Eberechi Eze, who fired a shot from the edge of the penalty area into the undefended net for a big three points.
Both players involved in the winning goal had to leave the field due to injuries, at the end of the first and beginning of the second half, respectively, which could worry Mikel Arteta.
Arteta's celebration at the end of the game speaks volumes about how important this match was for his team, as well as every subsequent one until the end of the season.
Arsenal are set to host Atletico Madrid in the first leg of their Champions League semi-final in just four days, and will then host Fulham in the league this weekend.
