But i think that can't be true. Why ??
Well now i will explain.
1. Adam never use the tricks , NEVER ! He don't know how any tricks does , but that is not real reason .
2. If tricks is R2+D-Pad they will have limited combination of ways to do tricks and they can't import new fresh tricks and will be same boring tricks since 98 !
3. May be true reason  to that no way trick  be only whit R2+D-pad because is nonsense. 
Look here :
In PES 2009 when you RUN - 

  you can make any trick like " Roulette " , flip flap  , " Lite Loop " etc. Just push the D-Pad in that direction and method as they do in principle . 
When you Run 

 + 

 after that push the D-pad some direction player do that :
Yes ,strong lead ?? It's Very useful !! One of the best PES movement , I love it ! Well try now to press 

 + 

 and try to make tricks when you RUN, roulette or anyone !! Yes 

 You can't , you will make that :
 
You guess what happened ?
If that what wrote in WENB is true  then Konami must remove tricks whit run and we will can make fients and tricks only when player walk , that will be very stupid 

 or they must remove " the strong lead " on the ball and that will be the EPIC stupidity !!! 

 If tricks will be on Right Stick all problems can be resolved and everyone happy.
