e I would be mad to turn down.
'I'm very excited, I can't wait to get going. I've been here two and a half years and it was kind of business as usual this morning.
'We've got some great players here at Portsmouth and I've been kind of responsible, with Harry, for bringing them to the club.
'I am going to take this opportunity and risk, because Harry's done a fantastic job for this club and is a hard act to follow. But I think it is my time, I think I am ready.'
