FREMANTLE will again be without Peter Bell for Sunday's NAB Cup match against Adelaide at AAMI Stadium – and without Paul Hasleby for the season – but coach Mark Harvey is looking to the future.

While Bell will play at Subiaco Oval the following Saturday, Harvey will be using the match against Port to trial young players. When asked exactly what changes there will be to the team that beat West Coast by 44 points, Harvey was cagey but did let out that young forward Chris Mayne will get his first run.

"No, [Bell] won't play. He will play the following week and two games before the start of the season," he said.

"There will be five or six players that will come into the side; I want Adelaide to do a bit of study on that, so I won't be saying who. Chris Mayne will play, that's one I will give, but there will be another five. That's exciting, because the more our members get to see our younger players play at this time of the year gives everyone a lift."

Hasleby's career was on the line at the end of a disappointing 2007 season, but he put in a massive pre-season and started the opening NAB Cup game against West Coast in brilliant form before rupturing the anterior-cruciate ligament of his left knee.

He has now had the reconstructive surgery and despite being a little indecipherable when Harvey visited him, will help out behind the scenes while preparing to return in 2009.

"He was in fairly good spirits, but having said that he was on the drip and wasn’t taking too much sense," Harvey said.

"Paul had set himself for a big season and the way he was playing suggested he would have one, but we can't harp on it. What we have to do is comfort Paul and get him through a series of things that will go through his mind.

"He was excited by how hard he trained and then how well he was playing. He will get back to that, make no mistake Paul Hasleby will be back. He will have a role in the coaching structure now helping out Peter German with midfield and stoppages. It will be interesting to have knowledge there and see what he has to say."

Harvey will continue to use the NAB Cup to experiment on and off the field. The midfield will have a new look with Des Headland, David Mundy and Michael Johnson in there, while the team will trial flying out a day before the game to see if it would help in the home-and-away season.

"A winning culture is what coaches and players look for, so if you can get momentum out of it it's a plus. The main motivation is to rehearse what we've practiced, learn how to handle to pressure and to apply a relentless outlook on how to play," he said.

"We are going a day out and seeing if that has any implications on the group and if it detracts from their performance. The guys themselves like it that way, but we will trial it in the pre-season and see how it goes."
