Ignore everything Peeps said it's rubbish.
Concentrate on trying to get as many strikers on the pitch as possible, and tell them to push high up the pitch and just pound the goal. Xpert is limited in that it won't let you put more than 3 (i think?) strikers on at once, but that's ok, you can just add midfielders and tell them to attack too. Defenders are pointless. Imagine Liverpool against Swansea. Try a 2-5-3 formation. You can bring on more attacking options via substitutions, but Xpert will only let you make subs after the 45 minute mark, so use them wisely. Three careful changes can turn that 2-5-3 into a 0-6-4, or "The Inverse Spain" as it is known.
Think Sherwood not Villas Boas. That'll get you through.
Good luck.
