Gabriel Martinelli capped off a memorable evening by celebrating with his dad, Joao, after Arsenal's last-gasp 4-3 victory at Luton on Tuesday night.
Martinelli opened the scoring at Kenilworth Road in the 20th minute, but Gabriel Osho brought Luton level five minutes later and the hosts twice went in front through Elijah Adebayo and Ross Barkley either side of a Gabriel Jesus equaliser.
Arsenal hit back through Kai Havertz on the hour mark, before Declan Rice popped up to head home a 97th-minute winner, sparking jubilant scenes in the away end.
