I was trying a 4-5-1v style few times and i have strong wings and striker (7*) and i was a litle stronger than my oponent (2-5 percents) and the AM evry time tels me that i shoud attack more and press oponent harder then i change in second half to 4-1-2-1-2 ND and win almost evry game....so i think if you do not have wings that have special abillity drible and striker with special abillity one on one you shoud avoid playing 4-5-1v style and play ND because you have way more chanse to score.
