Fremantle coach Ross Lyon has re-signed with the Dockers until the end of 2020, and says there’s no excuses for the AFL club not to taste premiership success within that time.

Lyon was already signed on until the end of 2017, but his three-year contract extension means he’ll be at the club for at least the next five years.

“Ultimately none of us are satisfied with where we’re at,” Lyon said.

“We’re certainly aiming for a premiership and we don’t shy away from that.

“Particularly by the end of this tenure, I’ll have no excuse to not have achieved that because we’re fully resourced, fully supported and I’ve certainly got a timeframe where we can make short-term and long-term decisions to shift us to where we want to be.”

The 49-year-old headed west from St Kilda ahead of the 2012 season and has taken the Dockers to four consecutive finals series.

Fremantle reached the grand final in 2013, and are expected to contend again this year despite the retirement of key defender Luke McPharlin.
