"He knows the situation. He understands there's not a lot of money, and that he isn't in the same position as other wealthier clubs," he told the Liverpool Echo. "You can either get all upset and resentful, or just get on with it and do the best job you can.
"That's Davie's approach. The biggest thing for any manager is to know what you have got.
"When you know what market you are shopping in you will work according to it.
"The difficult thing is when you don't know how much money you have got and then that becomes really tough, because you can find yourself looking at players you can't afford and it's a wasted exercise."
