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.

Esan Marsters
For the Tigers to build a side capable of a quick return to the finals they need to hold onto players like Marsters.
At only 21, the massive (understatement) centre is a must re-sign for the Tigers.
He played 13 times last year and scored five tries in a pretty fire attacking outfit. He will start the season in the centres again for the Tigers and with yet another pre-season under his belt should provide a real highlight for 2018, and hopefully beyond, in Tiger Town.
