"It's a position I've not been put in before. It's a real blow to the club."
He added: "It's like a massive cloud hanging over us. It's obviously affected my plans. And it's been very tough for everybody.
"But it's my job to get behind the players, focus minds and concentrate on making a good start to the season.
"I have to support the players. To get through a difficult situation. I'm a fighter and we'll get through it.
"I've got some big decisions to make over the next few months and I'll do my best to make the right ones.
"We've got some great people around the club and it's important that we get through this together."
