Arsenal beat Luton Town 4-3 right at the death in an absolute classic at Kenilworth Road on Tuesday evening.
Arsenal went ahead after 20 minutes when Gabriel Martinelli fired home neatly from Bukayo Saka's pull-back.
However, Luton started the theme of the evening by bouncing back straight away as Gabriel Osho headed one in from a corner, before Gabriel Jesus restored the Gunners' lead.
But the Hatters were level soon after as David Raya flapped at a cross - with Elijah Adebayo scoring - and then the Spaniard allowed Ross Barkley's shot to squirm underneath him.
