It was an expected result, since you don't have wingers. It's interesting that we have used the same formation in the past (4-5-1v) and are using the same formation at present (4-3-2-1). But then he could easily man mark the wide attack.
Anyway best of luck and use the lower level monetary bonuses, since now in match bonuses have more impact.
I'd suggest use the attacking bonus early. When you're 2 goals up don't use defensive, rather possession since it's better to lose the ball 55m away from your goal than 30m. It has worked for me well, with same formation.
I too had doubts suggesting 2 STs. But I'm a guy who'll attack the opponent's weaknesses than play to my strengths.
