Generally goal keepers do score low unless your opponent is having lots of shots and he is producing lots of saves, or he saves a penalty, so dont worry to much about that, as for your other players this can depend on them playing in the right position, being well trained,also when you buy players try to get the HOT PROSPECT players otherwise you could be buying other managers cast offs( the low rated academy players) that no body wants. Another thing is your team formation as well because some players score better in some formations and poor in others so its a case of trial by error till you get your best team!, the golden rule I have found is to buy young players, try to stay away from 4 & 9s as you end up in a bidding war and players cost you lots of tokens, HOT PROSPECTS or SCOUTS, when you can afford them and last of all and this is working for me have a minimum of 22 players, 11 first team and 11 sub/reserves at least 1 to cover every position of your first team. the reason for this is so I play my strongest team in the LG and my weaker one in the cups as the winning revenue is much better for the LG than the cups so this must be your priority!!!,.
You may think this a load of Waffle but I am on L6 having started level 1 half way through the season but still managed fourth, since then I have won 4 LG IN A ROW & CURRENTLY 11 POINTS AHEAD IN LEVEL 6, I try to go as far as I can in the cups but ALWAYS put my LG matches first, I have reached the quarter finals of the CL once but as long as I make the mini league of the CPL thats fine by me, I have been thoroughly honest in my tactics I hope it makes things a little clearer now Jim.
