Warnock admits he needs reinforcements with a host of weary stars nursing injuries.
He said: "We've made offers for a number of strikers and we have been looking at two or three strikers from home and abroad. They have to better than we have.
"But we are short especially as Marouane Chamakh has been out injured.
"We have lacked that physical presence up top. That will give us another dimension.
"We are also in for three or four left backs as I would like a natural left-footer as soon as possible.
"The players need a lift and helping out. They have dug deep. I've told them to hang in there and we have a good chance of improving the squad in the second half of the season.
'We're hoping to get one of those over the line in the first couple of weeks in the transfer window."
