WEST COAST youngster Liam Duggan has signed a two-year contract extension following a promising first season at the Eagles.

Duggan, 18, was the club's first pick (No.11) in last year's NAB AFL Draft.

The left-footer from the Western Jets in Victoria played 12 games in his first season.

"I couldn’t have asked for more in my first year, getting a look at a Grand Final,” Duggan told the Eagles' website.

"The only way it could have been better would have been to win the Grand Final and that has to be our aim. I really want to be a part of it."

"It's exciting to have extended my contract already, to get it done now so I can just concentrate on getting right for next year."

Duggan made his debut in round two and played 12 straight games before being rested in round 15.

He gathered 25 touches against Greater Western Sydney in round four and kicked his first goal against North Melbourne in round 10.

But on his return in the WAFL he damaged the posterior cruciate ligament in his right knee and was ruled out for the remainder of the year.

He was back on limited running duty by the end of September and is set to be eased into the pre-season.

"I'll probably be monitored at the start of pre-season," Duggan said.

"But I'm hoping to be fully fit by the time the Christmas break comes around."

The future looks bright for West Coast, as Duggan has joined fellow youngsters Dom Sheed, Jackson Nelson and Tom Barrass in signing contract extensions this year.

Eagles football manager Craig Vozzo said Duggan was a key pillar of the club's future.

"We see Liam as an important part of what we are trying to build," Vozzo said.

"We saw in the games he played this year that Liam has the class and skill to have a strong impact at AFL level – all the attributes that we were excited about when we drafted him this time last year.

"He is an impressive individual and a key plank in the exciting, young group we are building."
