Arsenal legend Ian Wright has praised Mikel Arteta for hiring set-piece coach Andreas Georgson.
The Gunners secured a fine victory over Leicester City on Sunday, with David Luiz scoring a terrific header from a training ground routine.
"It's no secret Arsenal have a set piece coach. When you look at how that [Luiz's goal] was worked, it was worked brilliantly," Wright told Premier League Productions.
"You can see that Lacazette was there to clear out the space and pin their best header of the ball which is Jonny Evans.
"And that is the space where you see David Luiz definitely waiting for the space to be cleared. The ball has to be pinpoint and it's fantastic. That's why you get a set piece coach, to get those things working on the training pitch."
