You played a formation with 3 attackers and a dmc, not exactly one that suggests double digit scoring. You're low level too so you're just going to whine more as you progress in the game and can't score more than 5 a game without tanking opponents.
You' won handily, didn't suffer an injury and your players rated well.
Please don't complain about winning games. I'll just make progressively more fun of you if you do.
