if the opponent is far too good, say you're 40 something and he's 50 something, go for 3 centre-halves, 2 wing backs, 2 central midfielders, a central attacking midfielder and 2 strikers. normal/defensive mentality(i never go defensive, mind you), through the middle, mark zonally because he'll beat your defenders in one-on-one situations. you could also overlap through the middle with your central centre-half and have a man over in attacks.
