Arsenal boss Mikel Arteta is delighted with the developing partnership between Gabriel Jesus and Kai Havertz.
For victory at Luton, Arteta declared Havertz turned his best performance for the Gunners.
On Gabriel Jesus, he said "He looked really lively today, really active and caused them a lot of problems. He was really mobile, a constant threat and scored a good goal. He was involved in many positive actions for the team as well, so I think we're getting the best out of him and he's in a good place."
On the link-up with Havertz for the third goal, Arteta added: "They have different qualities and complement each other really well. I thought Kai played his best game, he's getting better and better.
"That's what we need, players that start to raise the level and get in a good moment because we're going to need players as we're losing a lot at the moment."
