Fremantle coach Ross Lyon will hand club debuts to Cam McCarthy, Bradley Hill, Joel Hamling and Shane Kersten when the Dockers host Geelong on Sunday.

โ€œThe aim is to put it together straight away, but itโ€™s a work in progress,โ€ Lyon said.

โ€œItโ€™s not going to be perfect. But again weโ€™ve worked really hard.

โ€œUnder the fierce cauldron of an AFL game, thereโ€™s nothing that can substitute for that, and Iโ€™m sure weโ€™ll learn some lessons and look to improve.

โ€œThose four (new signings) will play, so itโ€™s exciting for us.โ€

After failing to play at AFL level in 2016, McCarthy has hit the ground running with the Dockers since joining the club, culminating in his six-goal performance against Carlton in their final JLT Series match.

โ€œConfidence is built by action, (and McCarthy) did all the hard work over summer,โ€ Lyon said.

โ€œHe didnโ€™t miss a session, and on all the metrics that get thrown around these days, he was high consistently. That gave him the best opportunity to perform well.โ€

โ€œ(Kicking six goals) certainly will make him feel good about himself but I loved Camโ€™s article over the weekend,โ€ Lyon said.

โ€œ(Cam said) Iโ€™m no-oneโ€™s saviour, Iโ€™m here to play my role and Iโ€™m not going to do that every weekโ€ฆbut it certainly builds belief.โ€

โ€œHeโ€™s got capabilities to grow. Heโ€™s only a young man, heโ€™s played a handful of AFL games really and heโ€™s only 21. Thereโ€™s plenty of growth in him.โ€
