The 20-year old played just over an hour of the Gunners' U21 teams meeting with West Bromwich Albion yesterday, marking his first match in about 14 months, and Burton feels it is a great moment for the club.
"It's like all players when they come back for their first game, they realise how difficult and tough it is," Burton told the club's official website.
"You always have to make that first step, and he has done that and that is fantastic.
"He is a quality player, it is great for the club that he has taken that first step on the road towards getting back into the first team.
"I think he is delighted to have been back on the pitch, as we all are.
"It is a start, now he just needs to keep working hard to play the football we know he is capable of playing, which we know is very exciting.
"What you can't duplicate in training is that match sharpness and players coming in at you, so he will have benefited from that in this match."
