Rangers winger Ryan Kent made an 'inexcusable' error in the first half of Sunday's Old Firm derby defeat, Ally McCoist has said. 

The lowdown

Rangers had the opportunity to go level points with their Glasgow arch-rivals at the top of the Premiership, but instead wound up falling six points back after a 2-1 defeat.

Aaron Ramsey had given them an early lead, but Tom Rogic quickly equalised and Cameron Carter-Vickers completed the turnaround shortly before half-time. With just six games to go, the Gers' title hopes are now looking somewhat slim.

Kent formed part of an attacking midfield trio in Giovanni van Bronckhorst's 4-2-3-1 shape, starting alongside Ramsey and Joe Aribo, and he completed the full 90 minutes.

The latest

With the score locked at 1-1, Kent was caught offside 29 minutes into the game after John Lundstram had tried to slip him through on goal, and McCoist, who is , was left deeply frustrated by that lapse in concentration.

On commentary for Sky Sports Football on Sunday [3 April, 12:30pm], as quoted by Ibrox News, Rangers' all-time top scorer fumed: "It's inexcusable. Goldson's done the exact same thing – you must look along the line.

"It's a brilliant ball from Lundstram. I thought, initially, the pass was for Bassey. You've got absolutely no need to be offside there."

The verdict

Kent is one of Rangers' star players. He ranks fourth in the squad for overall goal involvements (11) and second for assists (eight), and Transfermarkt rate him as the club's most valuable asset at £12.6m.

However, after he set up Ramsey for the opener in the third minute, it proved to be a frustrating day for the 25-year-old at Ibrox. He only completed two of the six dribbles he attempted, none of his five crosses found a team-mate and two of his three shots were blocked (via SofaScore).

He and his Rangers team-mates will now look to take out that frustration on Braga in the first leg of the Europa League quarter-final on Thursday.
