With literally millions of dollar of players off-contract at the end of 2018, clubs will be looking to lock their star players (or future star players) into long-term contracts. It's inevitable that players will move clubs however there are some players that just cannot be replaced.
Below is a look at the one player your club must re-sign. This doesn't have to reflect the biggest name off contract but more-so the player I believe each club should pull out all the stops to ensure they do not move clubs.

Brown had a magical 2017 season and will be heavily targeted if the Eels don't re-sign him quickly.
I was shocked his deal wasn't upgraded and extended following his 2017 effort, although given the faith the Eels showed in him I can't see him leaving the club.
That said, the likes of the Tigers, Titans and Knights are looking for game-changing signings and could do worse than offering big money for a big minute player.
