Rangers fell to a nightmare 4-0 defeat in Saturday's Old Firm derby, falling five points off the pace in the Scottish Premiership. 

Liel Abada scored twice while Jota and David Turnbull were on target too on a miserable day for the Gers.

With the inquest underway for Giovanni van Bronckhorst and his players, The Transfer Tavern use statistical specialists SofaScore to determine Rangers' three worst outfield players - will any of them be fearing for their place ahead of the Champions League curtain raiser at Ajax?

Antonio Colak - 6.1/10

Colak got his first taste of the fixture following his £2.25million summer move from PAOK in Greece, but it's one he may want to forget.

He recorded just ten touches but still managed to lose possession five times, completing a solitary pass across 60 minutes on the Parkhead pitch.

He also failed with the only dribble he attempted, lost four out of eight ground duels and came off second best in a third of his aerial battles (1/3).

And to compound matters, Colak missed a big chance to get Rangers on the scoreboard.

Glen Kamara - 6.2/10

Kamara's afternoon ended after 45 minutes, with Van Bronckhorst sending on Scott Wright in his place, and it's easy to see why the Dutchman took the decision.

He only managed 17 touches and 12 passes, and he didn't register any dribbles.

The duel statistics aren't pretty either - four contested, one won (1/2 ground duels, 0/2 aerial duels).

Malik Tillman - 6.4/10

And finally, there's Tillman, who, like Colak, was making his Old Firm debut.

The American, who's joined the Gers on loan with an option to buy, picked up a booking in the first half for a foul off the ball.

He too would be brought off before the end as Scott Arfield replaced him on the hour.

Tillman notched 25 touches and just 11 passes but was largely ineffective when running with the ball, completing just one out of four dribbles.

That was perhaps what really hurt his rating, because he did win six of his 11 duels (4/8 ground, 2/3 aerial).
