Ive lost only once, I have the following people on my team

tidus
brother
giera guado
jassu
botta
durren

Giera is good at everything
brother is good at shooting and catching the opponents ball, 25 i think
tidus is the best shot around like 50
jassu because hes an awesome defencive and attack stats
botta because the same as jassu
and durren because when i first got him he was at level 10 and had a catch of around 20! now he has like 35! hes unstoppable! no one ever gets a goal! MUHAHAHAHAHA
