I just have my best corner taker taking corners doesn't matter which foot or side. No OI instructions either unless you feel like doing it but the best thing is drop your best players if they can't play the positions and use players that can. Just because you like Memphis Depay doesn't mean you...
I'm playing as Dordrecht in Holland. I played with all my players being accomplished in each position and resulted in my annihilation. I think this tactic may be for teams that wouldn't lose many games anyway.
