He leaves a role at Exeter City to become a head coach in the Academy set up at Cardiff City.
He is one of just 16 coaches in the country to have been selected by the FA to undertake their pilot Elite Coaches Award course – the first Level 5 qualification to be aimed specifically at coaches.
Nicholson told http://www.exetercityfc.co.uk
“I’m delighted to have been given the opportunity to join a club the size of Cardiff City and to take on a very important role within their Academy. I’m excited by the prospect of the challenge and looking forward to getting started.
“I’ve thoroughly enjoyed my time at Exeter City – it’s a wonderful club, full of excellent people. It’s been a valuable experience for me and one in which I’ve learnt a lot. I’m sure that will stand me in good stead for my next challenge at Cardiff.
“I’m also sad to be leaving, because I’ve built up very good relationships with everyone at the club, including Steve Perryman and Paul Tisdale. I’ve had an excellent working-relationship in the Academy with Simon Hayward and I’ve really enjoyed working with the players. Everyone has been fantastic with me during my time here.
“Exeter took a chance on me back in October, when there was no other club prepared to do so at that time. I will always be very grateful to this football club and the people at the club for giving me that opportunity.
“Even though it’s only been for a short period of time, I feel privileged to have been part of this club.”
