Liam Morrison has lifted the lid on his sensational move from Celtic to Bayern Munich at the age of just 16.
The talented defender stunned Scottish football when he made the switch to the Bundesliga giants this month - just weeks after making his top team debut for the Hoops at their pre-season training camp in Austria.
Neil Lennon had voiced his frustration at Bayern's bid for the Scotland youth international and the Celtic boss vowed to fight tooth and nail to hold onto Morrison, adding that the Scottish champions were "not open to any offers for him".
But in the end the the stopper couldn't resist the lure of the Bavarian behemoths and agreed a deal which will see Celtic only due a relatively small development compensation fee.
Morrison has now opened up on his decision to leave his boyhood club - and leave his Celtic diehard gran gutted.
The teenager says the basis for his move is a desire to, one day, be the best defender on the planet.
"Celtic tried hard to keep me but my decision was already made as soon as Bayern came in," he told the Daily Mail .
"I loved every minute of my time at Celtic and I have to thank every one of the people I worked with who helped me so much.
"But when the Bayern offer came along, it's not really a club you can turn down is it?
"It was such an attractive offer. It was a no brainer for me and my family."
Morrison admitted his complete shock when his agent told him of Bayern's interest. "It was surprising when I heard. My dad and me were sitting in the livingroom watching football when a text came from my agent David Moss saying Bayern were interested.
"I turned to my dad and said, 'no way.' We decided not to read anything into it because it might be a daft rumour or something.
"But David contacted Bayern and came back the next day to say, 'yeah, they want you to come over and see the campus'. It was a dream come true for a club the size of Bayern Munich to be interested in me."
The teen, who used to attend Champions League matches with his gran - including a 2-1 defeat to Bayern Munich two years ago, added: "Gran is really gutted to see me leave. It was her dream to see me walk out at Parkhead to play for Celtic but she understood that Bayern was what I wanted."
Morrison points to former Celtic defender Virgil van Dijk as his role model and admits he too wants to be bracketed among the best on the planet one day.
Morrison will move straight into the Bayern Academy as he continues his development and growth as a young footballer. But he said: "The final goal for me is to be the best defender in the world.
"That is the ultimate goal. How I get there is by constantly trying to make myself a better player. Playing alongside great players can only help me in that respect.
"I take inspiration from Virgil van Dijk. He has been unbelievable since moving to Liverpool and you could see even when he was at Celtic what a great player he was.
"It needs so much hard work and I know I have a long way to go to get to where I want to be. I have to keep my feet on the ground and stay grounded and work hard."
