The teenage winger arrived in Glasgow with a reputation as one of English football's brightest prospects but struggled to make an impact during Martin's disastrous 122-day reign. By the time the former Southampton boss was sacked following a 1-1 draw at Falkirk, Moore had managed just six starts without registering a goal or assist.

Speaking to the Daily Record, the 19-year-old admitted his early displays were simply "unacceptable" and revealed the stinging message he received from his father after returning home.

He said: "Russell Martin has got his structure and his way of playing but I really respect him as a guy. I get it didn't go the way he wanted at Rangers. But he brought me to the club and I thought he was a really good guy. He tried to help me but obviously I wasn't performing my best.

"Maybe there were times under Russell I wasn’t playing in the best, best position to get the most out of me. But I've got to take responsibility for the way I performed at that time. No matter where I am put on the pitch, the standards I set for myself stay the same and the way I was playing at that point was unacceptable.

"Even coming home, my dad said to me, ‘I never want to see you play like that again, no matter where you are.’ I was very poor for the first few weeks but I can't blame me not doing my technical basics on the position a manager is playing me in.

"So yeah, I could have maybe played in positions that suited me better but you're never going to set the tactics as a player. Russell put trust in me and he called me into a few meetings to try to help me, but I've got to take responsibility myself and say I should have been better. It’s down to me really."

Martin's short-lived spell unravelled as Rangers dropped 13 points from their opening seven Premiership fixtures and suffered a humiliating 6-0 Champions League defeat to Club Brugge.

But despite the growing criticism surrounding the former Rangers boss, Moore was adamant that players cannot hide behind tactical excuses when their own performances fall short.

He added: "I think if you’re not ready to accept that responsibility, then it's a big problem for you as an individual. You can easily pass the blame onto other people and say that it's the manager or say that it's this person. But I'm on a football pitch with 11 players on each side. If I'm not affecting the game that's on me.

"There are things managers can do to help you out with, especially as a young player. But it's your job to learn your trade, learn how to play men's football. Obviously there are some tactical things that have an impact but ultimately it comes down to how much you want to run, how much you want to take care of your basics on the pitch.

"So for me I take responsibility for my first few months at the club. I'm never going to say it was Russell Martin's fault or someone else's fault. It was me who quite clearly wasn't technically good enough in a lot of games."
