Right, involves having Brother as your MF. It makes life a lot easier if he wins the blitzoff.
When he grabs the ball, (assuming you are playing the Ronso team in this example) simply swim past their MF, and then past all the other members of the team, close enough so they follow you. They will all give chase. Leaving your two strikers unattended (

)
Get a good gap and simply pass to one of them, clean shot on goal. Best if you pass to Tidus as he is faster.
This
should work all the time,even against the Guados and the Al Bhed, who can keep up with you. Obv the faster he (Brother) gets, the better. the MF player always levels up faster than anything else...
Best. Works for me anyway.
