Gabriel Martinelli FA Cup 2026 hat-trick lifts Arsenal past Portsmouth into fourth round

Gabriel Martinelli responded to a turbulent week in emphatic fashion, scoring his first Arsenal hat-trick as the Gunners came from behind to beat Portsmouth 3-1 and reach the fourth round of the FA Cup.

The Brazilian winger, criticised days earlier for an incident against Liverpool, silenced debate with a commanding display. Twice he rose to head home from corners before sealing the win with a composed finish, underlining Arsenal’s set-piece strength and his own resilience.

For Mikel Arteta, the performance was a statement of character. Martinelli has struggled for form in the Premier League, losing his starting place to Leandro Trossard, but remains prolific in Europe. His treble against Portsmouth lifted him to top scorer status this season, adding to five goals in as many Champions League appearances.

The atmosphere at Fratton Park was charged, with Portsmouth buoyed by an early lead and the home crowd sensing an upset. Arsenal’s response was measured, their midfield dictating tempo while Martinelli’s movement unsettled the Championship side’s defence.

Key incidents included Martinelli’s aerial dominance, surprising given his reputation, and Arsenal’s control from corners. Nicolas Jover’s set-piece coaching has transformed the Gunners, who have scored 17 goals from corners this season, more than any other Premier League side.

Martinelli’s first goal came from a well-delivered corner, his header precise into the far corner. His second followed a similar pattern, timing his run perfectly to meet another delivery. The third, late in the game, showcased his composure, finishing calmly after a swift counter-attack.

In the second half, Portsmouth pressed but Arsenal’s defence held firm. Martin Ødegaard orchestrated play, while Declan Rice provided balance in midfield. Arsenal’s control grew as the match wore on, their dominance reflected in possession and chances created.

Late drama was avoided as Martinelli’s third goal ended Portsmouth’s resistance. The Gunners managed the closing stages with maturity, ensuring safe passage to the next round.

For Arsenal, the victory extends a remarkable run in cup competitions, with nine wins from ten matches this season. Top of both the Premier League and Champions League groups, they now face a demanding schedule with four away fixtures across competitions.

Martinelli’s hat-trick was Arsenal’s first in the FA Cup since Theo Walcott in 2017 and the first time the Gunners scored three from corners in a single game since 2022. More importantly, it reaffirmed their attacking depth and Martinelli’s ability to respond under pressure.

Arsenal’s pursuit of silverware continues, with Arteta’s side well placed on all fronts. For Martinelli, this was a night of redemption, turning criticism into celebration and reminding supporters of his enduring value to the team.
