Your striker won't do much in that formation, but your wingers should score tons. I have the same formation and my right winger is top scorer in the league and my left is like 3rd.

5 stars is a good player in the first level, you can concentrate on swapping out your players at the beginning of the season, save your tokens and buy up 2 wingers and a couple other players. They are cheap at that level and you shouldn't have any problems picking up 6-8 players at 5 stars. Try and get some youngish players with 95% quality and they will rain up fast. Remember that price includes training ability, so getting a cheap player never works for too long. I bought a great but expénsive 18 year old, and watching videos and playing 2 games a day he's already world class in the same season.

By all means tho, stick around.

I started my first year about 5 games from the end and only just qualified....second year I finished second and got into the champions league....3rd second again with champions league experience, 4th 2nd again but only by one point....5th season I'm almost in the cup, champions league finals and 10 points clear.......each year I've learnt something new. The difficulty level hasn't changed a lot though, as I was always up against people buying their teams for a while, so it took me some time to replace my players. Now I'd really like to be in the 20s, and feel a real challenge to qualify for the champions league etc, is far off.
