Perhaps we can control the fan too by throwing the beach ball inside opponent penalty area 

lol

perhaps steps by steps 1st.

I hope they can change the commentary (most important!)

Then they add in more animation, plus some natural gesture of the players (i.e. pushing each other during corner kick, goalkeeper point and shout defender to mark nearby opponent during free kick, players argue/blaming each other when concede goal...etc.)

Then add more license clubs.

The other more details one can just add in one by one on latter title.

Those 3 main things should be the priority for WE/PES2011 improvement
