Depends on the team, Geoff.
I would say the best team to play attacking from the wing has to be Chelsea.
Formation as follows;
Select 4-3-3. while doing this move the d-pad across and select 4-3-3 T.
Go to 'Select Role' and, if not already positioned, select the following;
GK - Cech
CB - Terry
CB - Carvalho
RB - Ferreira
LB - Del Horno
CM - Essien
DM - Makelele
AM - Lampard
RWF - Robben
LWF - Duff
ST - Drogba
Go to Quick Formation and select 'Side Attack'. Adjust the individual attacking strategy as appropriate (eg. When selecting 'side attack' the full-backs are set to attack backwards as well as forward. So set them to run forward and diagonal forward.)
Hope this helps, squire...
