"I don't think there's been a doubt in our minds about our ability to achieve results," he said. "I know the players are relieved [to win], they're only human beings.

He added: "I think it is going to be important for us to try and strengthen and add to what we already have, because if we can add quality in one or two areas, I think that’s going to help the players that we already have.
"I am not suggesting our players aren’t good enough, I know that they are.
"We have got some talented players but to be consistent in this division it is very hard."
