North Melbourne have extended the contract of defender Marley Williams who has inked a one-year deal to remain at Arden Street.

Williams will play his ninth season of AFL after putting pen-to-paper on a deal that will last until the end of the 2020 season.

โ€œWe did start chatting late last year and I got lucky enough to get another year at the club,โ€ Williams told North Media.

Williams expressed his delight to extend his contract with North Melbourne, admitting he has exceeded his own expectations.

โ€œI actually didnโ€™t think Iโ€™d get this far in the AFL,โ€ he said.

โ€œI donโ€™t think anyone really thinks about it too much but Iโ€™m just really happy and privileged to be able to get into my ninth season next year.โ€

Williams added he has enjoyed the new culture under interim coach Rhyce Shaw, with the team and finding a reinvigorated run of form.

โ€œWe used to be pretty good mates but I donโ€™t know if I can say that now heโ€™s head coach,โ€ Williams joked.

โ€œWeโ€™ll stay close and keep it professional now. Just being able to play for him as a head coach is huge, I love him as a bloke, heโ€™s made great relationships and heโ€™s just so easy to play for.โ€

Williams, 25, has played 113 games, 45 with the Kangaroos, and believes the side is closer than ever.

โ€œWe are a really tight group and we came together as a team and spoke about a few simple things and weโ€™ve just stuck to it,โ€ Williams said.
