Did you edit the database to include Beckford on loan untill January (I may mistaken but I believe that's when his loan ends) If so among him and Vaughan you've got a good set of strikers. However, I have signed Eric Ljiac for Villa for about 600k and David Petrucci for United for 800k. They both fit Deano's requirement for new signings to be young and help witht he attacking brand of football. Would also recomend Sean Morrison and Lewis Dunk if you can prise them away from Reading and Brighton respectively.
Hope this helps and you have more luck than me with results (On a 5 match loosing streak currently after not investing enough in my defence)
