Rangers slipped six points behind their arch-rivals at the top of the Premiership on Sunday as Giovanni van Bronckhorst’s men lost 2-1 at Ibrox.
The Gers failed to make the most of their early advantage as they allowed the away side to come back from 1-0 down.
Aaron Ramsey had put Rangers in front early on with a smart finish at the front post, but goals from Tom Rogic and Cameron Carter-Vickers ensured that the three points went to the Hoops.
They are now six points and a significant goal difference gap below Celtic and their chances of sealing the trophy for a second successive year appear slim at best.
One player who let van Bronckhorst down badly and is, subsequently, costing the side the title is centre-forward Kemar Roofe.
The striker put in a poor display in the Old Firm clash and cost his team for the second time in this fixture since the Dutch head coach arrived.
On the ball, he offered very little. As per SofaScore, he had fewer touches (26) than Allan McGregor (32) as the striker completed nine passes. He managed three efforts on goal and all of them were off target, with one of them being a big miss as he fired a volley over from eight yards after an excellent cross from Connor Goldson.
This shows that he struggled to impose himself on the game as Carter-Vickers and Carl Starfelt dominated him throughout. He was unable to showcase his quality in possession and that played a major role in the result as he did not make the most of the service he was provided with.
Against the ball, he was a lightweight. As per SofaScore, he lost a whopping 70% (7/10) of his individual duels as he was dominated by the Celtic centre-backs.
This was not a one-off for the attacker as he also had a shocker in the 3-0 defeat to the Hoops back in January. As per SofaScore, he lost 70% of his duels in that game as well, whilst failing to register any shots or key passes.
He has only started two Premiership games under van Bronckhorst and both of them have been huge games at the top of the table, with Roofe’s lack of quality at the top end of the pitch costing them both times. If you turn both of those defeats into wins then the Gers would be six points clear, themselves, and that is why the flop’s dismal showings have cost the head coach the title.
