“I didn’t know Darren before taking the job, but I know we’ve got lots of mutual friends in the game who have obviously been colleagues of both myself and him.
“Everybody speaks so glowingly of him, which is one of the reasons why I was so keen to meet up and see what his vision was - and I was really impressed.
“I had a really good feel about it having spoken to him. I had a few other offers but this felt right.”
