Football Manager 2006/07, playing with Manchester United?

Have tried several formations but not winning many games. Lots of draws with my defense saving the day. Playing Ronaldo at Left MF attacking (Giggs off the bench) but Ronaldo isnt scoring much and neither is Rooney at forward . Playing Park Ji Sung at right wing but he isnt playing well either. Is there a better formation than the 4-4-2 or 4-5-1 that I am using? Is there a player i can buy for the right wing that works dynamite? Appreciate the help.
