As part one and part two of this player preview has already been done, all that's left is to preview the remaining four teams that will make up Super League in 2018 and a player from each of these sides that has the potential to be their team's stand-out figure in the new season. The last four, alphabetically, will see players from Wakefield Trinity, Warrington Wolves, Widnes Vikings and Wigan Warriors. Trinity definitely impressed the most out of the four in 2017, narrowly missing out on a top-four spot whilst the remaining three - particularly the Wolves who suffered the ignominy of the Middle 8s Qualifiers for the first time - had bitterly disappointing seasons.

The four players below could prove to be the ones that can propel Trinity and Wigan into the top four and Warrington and Widnes into the top eight.

Wakefield Trinity - Tom Johnstone

After being sidelined for most of the 2017 season with a serious knee injury, Tom Johnstone will be looking to rediscover the form that had many pundits and fans purring and a number of top-flight sides chasing his signature. In 2016, the winger notched up 20 tries in 25 appearances to be crowned Super League's Young Player of the Year and proved key to Trinity's top-eight finish and Challenge Cup semi-final appearance.

A winger with unbelievable pace and an ability to finish off tries like few in the game, Johnstone - still only 22 years old - is confident he can make Trinity's Round One opener against Hull FC in February.

If he does play that game and if he can regain his confidence that belies his youthful age, there will be no stopping Johnstone in 2018.

Warrington Wolves - Daryl Clark

Since moving to Warrington in 2015, Daryl Clark has been somewhat of a disappointment for the Cheshire club.

With Tony Smith leaving the club at the end of 2017 after a dismal year and with new boss Steve Price determined to make the Wolves "attractive to watch", however, it could be the time for Clark to show the form which had once earned him the Man of Steel award back in 2014.

Appearing shackled under Smith, Clark's talent has been left on the backburner for the past few years.

But, with Price illustrating his desire to instil a new, exciting culture into the Wire side, Clark's real potential could finally come to the fore for the Wolves in 2018. And, from his time at Castleford, all of Rugby League knows what a Clark firing on all cylinders could mean for a Warrington side aiming to drastically improve on 2017.

Widnes Vikings - Joe Mellor

Widnes's pains were quite obvious in 2017; a seemingly endless injury list consigned the Vikings to bottom place in Super League. The Cheshire club could hardly have got off to a worse start with the news that new co-captain and the new no.6 Joe Mellor - replacing the Warrington-bound Kevin Brown - would miss the first six weeks of the 2017 season with a knee injury.

With Brown departing, Mellor would be the player that Widnes would rely heavily upon to secure their top-flight status.

Mellor - though absent until early April - still managed to appear 18 times, scoring eight tries and, crucially, steered the club to an automatic promotion spot in the Middle 8s Qualifiers. If Widnes are to escape the Qualifiers once more in 2018, or, even obtain a top-eight spot in Super League, Mellor has to be at the top of his game. Free from injury, and at the prime of his career - aged 27 - Mellor could well be the Vikings' saviour in 2018.

Wigan Warriors - Morgan Escare

Goal-kicking full-back Morgan Escare moved to Wigan from French side Catalans Dragons at the end of the 2016 season.

With Sam Tomkins sidelined through injury, Escare took his opportunity with both hands at the beginning of 2017, starting 13 games at full-back where he scored four tries and kicked 33 goals. An impressive string of performances was enough for the Frenchman to earn a new contract to take him to the end of 2020. In a cruel twist of fate, however, Escare's season was cut short in late April when he suffered a season-ending injury.

When fit, Escare has shown more promise in the 13 games in which he has donned a Wigan shirt than Tomkins has since his return in 2016. With electrifying pace, flair and composure in abundance and a defensive ability that belies his small stature, Escare can take the No.1 spot - if not the shirt number - from Tomkins in 2018. If Escare can cement his spot in the first-choice 13, the Warriors will have a seriously exciting player that could help steer them back to the top four after a disappointing 2017.
