LONDON — Christian Pulisic became the first American to score a goal in an FA Cup final, but he never saw the end of the game after suffering a hamstring injury Saturday.

The U.S. international midfielder struck for a brilliant goal in the fifth minute for Chelsea in its 2-1 loss to Arsenal at Wembley Stadium. He needed to be helped off the field early in the second half.

Only five minutes into the match, the 21-year-old Pulisic started his own scoring sequence with pass to Mason Mount. Mount then found Olivier Giroud in front of the net with a low cross. Giroud flicked the ball to Pulisic, who slotted the ball past goalkeeper Emiliano Martínez for a 1-0 lead.

Pulisic became the youngest player to score in the final since Cristiano Ronaldo tallied 16 years ago

The goal was Pulisic’s 11th goal in 33 matches across all competitions this season.

Pulisic almost found the net again for the Blues in the opening half. He couldn’t reproduce that magic again, but then again, neither could his teammates.

Pierre-Emerick Aubameyang , however, tallied twice, in the 28th and 67th minutes to boost Arsenal to the victory.

After sitting out with his teammates and the rest of the sports world for more than three months due to the COVID-19 pandemic, Pulisic returned to the game with a passion, either filling the net or setting up teammates. Chelsea finished fourth in the English Premier League, securing a spot in the 2020-21 UEFA Champions League.
