After helping West ham to promotion, the England under-21 international is aiming to help the Gunners to their first trophy in eight years
The 21-year-old spent last season on loan at West Ham, as they won promotion back to the top-flight via the play-offs and Lansbury believes the experience will prove to be invaluable as he begins the fight for a place at the Emirates.
"It's always nice to play for the club you have been with for so long, and hopefully I can put on the shirt many more times," he told ArsenalPlayer.
"To get another promotion was great. It was a good experience for me at West Ham."
Lansbury scored against Anderlecht in Arsenal's opening fixture of the Markus Liebherr Memorial Cup at St Mary’s Stadium, and could have added to his tally against Southampton in their second game.
"It was a great opportunity for the lads to get some minutes under their belts and to win [the Memorial Cup] was a bonus," he added.
"The goal came after a good cross by Jenks [Carl Jenkinson] and it was nice to get on the end of it.
"I should have scored [against Southampton] as well, but I thought the keeper would clear it. I got a bit excited and fell over!"
