The Eagles are in the drop zone only on goal difference after winning their last three home games ahead of Saturday's visit of Hull.
But Burley knows he must beef up his thin squad if they are to maintain their upward surge.

"But I think there have been some encouraging signs of late and it's the perfect time to build a squad up which is going to do well in the Championship."
