Best way/(s) to play against 4-1-2-1-2 wide diamond...

[Tactician]

I started with 4-5-1 V-style. The pressure was on my team. Later in the game, I switched to 4-1-2N-3, and my team conceeded a goal which was the only the goal of the game. I am disappointed though because I think for this level of the game, I should have won it. The opponent was weaker than my team, but this maybe just visual as I suspect something like percentage efficiency in this game. My ST and AML was at scout level (6 stars) and AML was at world class level (7 stars), but they failed to trouble the opponent; they were 'absent' from the game.
