MATURE-age draftee Zac Langdon will fulfil his AFL dream on Sunday when he makes his senior debut with Greater Western Sydney against the Western Bulldogs.

Langdon, 22, was taken at No.56 in the 2017 NAB AFL Draft and has enjoyed a strong pre-season, playing in both JLT Community Series games after relocating from Western Australia.

GWS football manager Wayne Campbell hailed Langdon's instant impact at the club following two seasons with Claremont in the WAFL.

"His work rate on the training track has been impressive throughout the summer and the professionalism he has shown since November has been a real standout," Campbell said.

"He replicated that form from the training track in his two JLT outings and showed he's ready to handle the rigours of the AFL.

"We believe his defensive pressure is something that can really add to our forward line too."

Campbell said Langdon, who was training as an apprentice electrician before committing to the pursuit of an AFL career, had benefited from arriving at the elite level with extra experience.

"Being 22 and having spent time in the WAFL means he's come to the club with a real hunger and energy, and everyone around the club really noticed that from the day he walked into the club," Campbell said.

"While all draftees need a bit of work when they first arrive, Zac came with a bit of an advantage by having a more mature body."
