Declan Rice scored a 97th-minute winner for Arsenal to break Luton Town’s hearts and pick up a 4-3 win on a dramatic night at Kenilworth Road.
Luton had looked on course to land a thoroughly deserved draw after two errors from Raya had seen them hit the front – only for the Gunners to rally and win it 4-3 at the death.
Raya embraced Rice at the full-time whistle after Kai Havertz had earlier drawn the visitors level in what proved to be a thrilling contest at Kenilworth Road.
The visitors had led 2-1 at half-time as Gabriel Martinelli and Gabriel Jesus scored either side of a Gabriel Osho equaliser.
Raya, whose role as Arteta’s number one continues to be in the spotlight with Aaron Ramsdale warming the bench, then gifted two goals to Luton in the space of eight minutes as Elijah Adebayo and Ross Barkley turned the game on its head.
Havertz appeared to have salvaged a point for Arsenal but they pushed on to the last and £105million summer signing Rice nodded in a fine Martin Odegaard cross to wrap up the victory.
Having seemingly spent more time on his back than on the ball, Martinelli silenced a raucous home crowd with the opening goal.
It was Arsenal pushing for a late winner and Kaminski turned a Havertz header over at the end of a slick move.
Rice would ultimately make the difference as Arsenal were patient in their build-up, Odegaard swapping passes with substitute Oleksandr Zinchenko before crossing in for Rice to head home.
