Glasgow Rangers head coach Michael Beale suffered defeat for the first time in charge of the club as his side lost the final of the League Cup 2-1 on Sunday.

Their opponents took the lead just before half-time as the Light Blues fell asleep in their own penalty box and allowed Kyogo Furuhashi to arrive unmarked to tap the ball into the net from close range.

Celtic punished them again in the 55th minute. Kyogo scored his second goal of the match by sliding in ahead of Borna Barisic to meet Reo Hatate's cross.

However, Rangers reacted brilliantly to pull one back almost immediately. Alfredo Morelos met James Tavernier's set-piece and put his side back in the fight by converting at the back post.

Whilst it was a performance that was full of disappointing performances across the park for the Light Blues, one player let Beale down badly in the heart of the defence - Connor Goldson.

How did Connor Goldson perform against Celtic?

The manager's veteran defender, who has played over 250 competitive matches for the club, did not showcase his leadership and experience for the Gers as his sloppy defending ultimately cost the club a trophy.

Goldson will not want to see the replays for the opening goal from Kyogo as the Englishman was caught horrendously out of position, which allowed the Japan forward to put their rivals ahead.

Ex-Gers winger Neil McCann criticised the central defender's role in the opener, saying:

"Connor Goldson is right out the game. Kyogo just walks into the box and it's the easiest tap-in you could have in any game, never mind a cup final."

Journalist Jonny McFarlane added to that by Tweeting that it was a "terrible" goal to concede as the ex-Brighton man was in "no man's land" at the back.

The £37k-per-week enforcer was then part of the defence that failed to cut out Hatate's ball along the box for the second goal, although Barisic was the closest man to Kyogo for that particular strike.

Goldson also did little to stop Allan McGregor from being tested as the Hoops had a whopping 14 efforts on goal, including five on target, which suggests the 30-year-old did not do much to make up for his first-half error.

Therefore, the English defender was a big liability for the Gers in the match as his lapse in concentration broke the deadlock in the match and allowed Celtic to kick on and dominate the match. His error let Beale down as the manager may not expect one of his most experienced players to make such a telling mistake.
