Ok so i have NO IDEA weather this will work or not but if your willing to lose a game and win a game,

If you have a player that you want to get LOADS of goals without playing many games then theres this method is what you need

for example i have Heskey and i want to get him to about 100-200 goals but can't be bothered to play so many games, i just want to show him off to my mate.
you find someone to do it with, find each other in game somehow and score as many goals as possible with Heskey then you do it again and the other person gets the goals

Or you could make sure it's a draw and go into extra time just to be sure the person your doing it with won't get his goals and leave.

Anyway i think i've explained everything,

I am willing to do this, PM me, or post on this topic to bump it up and then other people can see and do it with you!
