I have lost 5 of last 6 finals on penalties. Always seem to miss loads. How do i improve my chances in them? is it down to shot accuracy and shot power ratings?

Penalty kicks depends on shooting accuracy & power for sure!If ur players have better shooting skills they have a better chance for sure!
The goalie,is very very important too,Higher the skill & the acquiring of special abilities of Penalty kick,sure the better he have a chance to save!
If U want to improve ur chances,try adding penalty kicks to ur goalie as a special ability,also work on the shooting skills for ur players!
best luck!

penalty kicks depend on random. Once I won when I had goalkeeper from school wih skill 38
