see whos available on free transfers theres usualy some bargains about , Also if u can get Danniel Prejo (spell) from real madrid avaiable for about £1k takes a few games to settle in but hes very good averaging 8 for me .
Others u could try are Krivets , Laurito , Fiorillo , Lewandowski , Kadlec , Alibec and then see who u can get on loan from other clubs Gibson , Fabio , Macheda from Man U Simpson , Nordviet from Arsenal and Jimmy Smith from chelsea , there not bad players , good squad players
hope that helps
