I've told you all i can told you, for my side...
I'm agree with little dude, faith, faith and faith, try to know your players, that makes the difference, and yea, always the same when season start, team don't works like at the end of season. You know my opinion, train 1st the speed at max.(res, straight, agr, creat...all that)
and, with the 4-3-3, or with another formation,there's no a "perfect" formation, that's a simulating game, so try to work in this sense, if you have 6 St 6 MC, sure 2 are good, and sure 1 ST is good making goals at the end of the match playing only 15-20 minutes.

Think that, a 4* player can be better than a 7*, so, a 2* defense against 5* ST is the same. and, that's my opinion, like eveyday, now you decide in the way you wanna work.

PS added; not agree with littledude about arrows, put arrows, give arrows, arrows as a present for everybody! party forever! LOL
arrows for me are = options, full arrows (for me) are regular lines.
