West Ham boss David Moyes insists he has the backing of the board as he seeks to strengthen his squad this month.
"The board have backed me greatly since I have been here, anything I have really asked for," said Moyes.
"But I also know I am not someone who is going to go and ask for money in a period of time in football where wages can't be paid.
"Do I want a top striker? I certainly do, I really do, to help us. But I am also mindful that football clubs, a lot of them are on the verge of going bust and I have got to make sure that I do things correctly.
"I think we are in a difficult period. January often hasn't been that good a month. It was good for us last year, so trying to get the right player is not an easy thing.
"But I have got to say the board has definitely tried to support me and back me in getting players in."
