no prob
First thing I would do is address your back line. Having only two players that play Defensive back on your team is going to cost you. I'm not sure what the ideal amount is but I'd recommend at least 5 DC's for a 3n-4-1-2 to cover injuries and red cards. Being able to play a back four (DL DC DC DR) isn't a bad option either for more increased defense against strong opponents using 3 strikers or 2 strikers and a motivated AMC, since you want +1 defender for your opponents strikers to act as help defense for when your DC gets beat.
