Glasgow Rangers endured another difficult night in the Champions League at Ibrox as they lost their fourth group stage match of the season.

The Light Blues were hammered 7-1 by Liverpool on their own turf, a week after losing 2-0 to the Premier League outfit, as the Reds came from behind to win the match comfortably.

Scott Arfield had given the hosts the lead after 17 minutes when he fired past Alisson and the score was 1-1 at half-time, which put Gio van Bronckhorst's team in a great position to win the game heading into the second half.

Instead, they capitulated as Mo Salah came off the bench to score a six-minute hat-trick and Jurgen Klopp's team scored six times in the second 45, with Allan McGregor conceding seven of the nine shots on target against him.

Whilst it was a disappointing night for the 40-year-old, as Liverpool's players beat him with ease, another player was the true villain of the night for the head coach - Antonio Colak.

The Croatian has been in phenomenal form this season, with ten goals in nine Premiership matches and is the type of player who Rangers need to be on top form to get a result in big games.

Instead, he let van Bronckhorst down with a shocking performance in the number nine position, as he struggled badly in and out of possession in his 76 minutes on the pitch.

Off the ball, he was dominated by the opposition and failed to hold his own. Reporter Joshua Barrie noted that the team had no outlet to hit at the top end of the pitch and Colak's statistics back that up as he lost a whopping 12 of his 13 individual battles - including nine of his ten in the air.

This meant that he could not hold the ball up to allow the rest of the team to push up the field, which allowed Liverpool to press higher and higher until they pinned the Light Blues in their own third of the pitch.

In possession, the dud failed to deliver when it mattered as he missed a 'big chance' to make it 2-0 after Arfield's opening goal, as his effort went wide of Alisson's post with only the goalkeeper to beat.

The mentality of both sets of players may have changed if he had converted that opportunity and the entire game could have been different. Instead, Roberto Firmino equalised shortly after that and the rest is history.

Colak also struggled with his passing as he completed 50% of his ten attempted passes and lost possession seven times from 15 touches - conceding the ball every 2.1 touches.

The former PAOK dud failed to live up to the high standards he has set in Glasgow so far as he let the manager down which is why he was the villain of the match, as he negatively impacted the team's chances of winning in and out of possession.
