Warburton exit was not in the script for Burt . . .

T2 Trainspotting has many moments where the audience are shocked ... but that was nothing compared to the jolt Rangers starlet Liam Burt had moments before he went in to watch the film . . . he’d just learned his mentor Mark Warburton had left Ibrox.

Burt was handed his Rangers breakthrough by their former manager, who is now locked in an increasingly bitter battle with the Ibrox club amid claim and counter-claim.

The 18-year-old midfielder and Scotland Under-19s captain was hailed by Warburton as a “real talent” when he signed a new deal at Ibrox last year.

And Burt, who is set to play for Scotland in their final Elite Group game in the Czech Republic against Hungary tonight, has revealed the bizarre circumstances when he found out about Warburton’s departure.

Burt said: “I’d trained as normal on the Friday and later on I’d gone to the cinema to see the new Trainspotting film. I was walking up the stairs when I got a message through saying the manager was gone.

“It came out of nowhere and I was probably as shocked as everyone else. I thought that it was a joke until I’d checked it out myself. I still managed to enjoy the film! My head was all over the place but it was a good film.

“My debut for Rangers was a proud moment. I was grateful to Warburton.”

Now Burt has to prove himself to new boss Pedro Caixinha.

He said: “It’s been really good training under the new gaffer. He’s brought new ideas.

“I’ve not had the chance to speak to him on an individual basis yet because he’s had a lot to do.

“The training’s probably more attack-orientated. Mark Warburton wanted to attack but to keep the ball in the process. The new manager is maybe a bit more direct.

“The training is sharp. Some of the drills take some getting used to but that’s only because we’re new to them.

“I think I’m improving all the time through training with the first team. Playing against bigger, stronger players makes you think quicker and move the ball on a second earlier.

“The senior players have all been great with me.”
