To raise funds I sold Maros Klimpl, partly for funds, and also he was taking up a lot of the wage bill. With that I signed Darryl Duffy from Bristol Rovers, and Ferydoon Zandi from Tranmere. Although if yiu cant get Verratti, try Mats Rits. I kmow Verratti a CAM, and Rits is a CM- but he becomes a beast. Also Ki Sung Yong is very very good is you can get him on loan from Celtic. Other players are Suso from Hearts(maybe too expensive) and Stefano Napoleoni from a Greek Team, sorry I forgot which one- I regret selling Napoleoni, he's currently top scorer in SPL, with Hamilton.
Hope thta can help, I know I anmed a lot of players- and sorry if that bombards you with names, but the key ones from there are Ki Sung Yong and Napoleoni.
