Although coach Mikel Arteta made 10 changes in the starting lineup compared to the draw with Liverpool in the Premier League, Arsenal is still rated much higher than Portsmouth - a team playing in the Championship. However, the reality on the field is not easy for the away team.
In the 3rd minute, Portsmouth surprised when Colby Bishop took advantage of goalkeeper Kepa's indecisive save to open the score, putting the home team ahead to the excitement of Fratton Park fans. In the first 20 minutes of the match, Arsenal played clumsily and almost did not create significant opportunities.
The turning point came from set pieces - the familiar weapon of the "Gunners". In the 16th minute, from Eberechi Eze's corner kick on the left wing, the ball touched Andre Dozzell, changed direction and flew into the net, helping Arsenal equalize 1-1.
Just a few minutes later, the away team continued to take advantage of corner kicks to take the lead. Noni Madueke crossed the ball accurately for Gabriel Martinelli to cut and head, increasing the score to 2-1.
At the end of the first half, Arsenal had a chance to increase the gap when they were awarded a penalty, but Madueke's shot went wide of the post.
In the second half, Arsenal played more proactively and effectively. In the 51st minute, from a quick free kick situation, Gabriel Jesus assisted favorablely for Martinelli to tap the ball close range, complete a double and increase the score to 3-1.
In the 72nd minute, still from a corner kick, Martinelli continued to head into Portsmouth's net, closing the first hat-trick in his career and sealing a 4-1 victory for Arsenal.
This victory not only helped Arsenal win a ticket to the next round of the FA Cup, but also showed their advantage in set pieces.
In addition, the "Gunners" also welcomed good news when Kai Havertz returned to play after injury, adding a plan for the road ahead of the season.
