Snapped up from Hamilton he became a leader of the team as a teenager and provided decisive and memorable moments throughout the campaign. Rampaging full-back gave Dons real intensity and thrust down the left. He may have cost 9million but will earn Celtic a profit. Fantastic striker. The centre-back oozed class and developed a strong partnership with Dedryck Boyata, One of few good decisions made by Dundee this season past. One of the better full-backs in the league. Accies have struggled for a reliable right-back during their time in the Premiership but found one in McGowan.Chipped in with goals and assists. Played a big part in Accies' survival, including one of the goals of the season against Aberdeen. Plucked from the Austrian second division, turned into a commanding presence in the centre of midfield. The club's top scorer despite missing chunks of the season which hurt the Jam Tarts. Thirteen goals from midfield. A danger anytime he picked up the ball around the opposition box. The Belgian midfielder became a fans' favourite with his all-action displays. Eight goals in 16 games fired Killie into title contention then moved to Aberdeen. His form prompted a Scotland call-up. Ideal goalkeeper for Livi. Livi's best player in the second half of the season when moved into the centre of midfield. Dynamic and combative. Took over from Trevor Carson and never let Well down. If Carson was fit it would be hard for him to regain his place. The Steelmen's most consistent centre-back. Strong in the air, good on the ground. One of the reasons Rangers' defensive record improved drastically, from 50 to 27. Signed from Dundee half way through the season, adding quality to the Rangers midfield with his composure and dribbling ability. The best goalkeeper in the league during the 18/19 season. Needs to stop kicking opponents. Helped make St Johnstone really exciting to watch with his wing play. Injury robbed him of a large chunk of the season. Saints' best and most consistent attacker. Played wide and as a No.10, was excellent at driving at defences. Showed himself to be a hugely talented goalkeeper after signing in January. Was the hero of the club's play-off win over Dundee United. Scored a few crucial goals to prevent St Mirren getting cut adrift. Two of which were long-range crackers. Left in January but made an impact. A solid and confident presence at the back. Scored a penalty in the shootout to keep the club in the division.
