PORT Adelaide has shown faith in emerging big-bodied midfielder Brendon Ah Chee, re-signing him for next season.

Ah Chee drew a line in the sand this year, stating early that the time had come to break into the senior side.

The 21-year-old has played eight games this year after making his AFL debut in round three. 

"On a personal note, I'm pretty happy with how my year has gone, pre-season was a massive win," Ah Chee told the club's website.

"With that comes fitness - I was fitter than I'd ever been - but also something that comes with that is confidence, which is even more important. 

"In previous years I've been starting behind the eight-ball in terms of fitness and structures, but this year I'd been in the thick of it since the beginning, which allowed me to put my best foot forward."

Coach Ken Hinkley has publicly said that he'd like to improve Port's depth of inside midfielders.

Ah Chee, who was recalled to the senior side to face the Giants this week, has the opportunity to "own" a midfield position by performing well in the remaining four games of 2015.

That's exactly what he plans to do. 

"It's been eight games this year, so I'm pretty happy with that, but I also want to keep getting better," he said. 

"Consistent footy is my 'number one' priority for the rest of this season."
