From what I’ve seen it’s more of a 3-4-3.

It seems to be our only way of scoring is getting crosses into the box. So therefore we need to increase the number of people in the box , so we should play 2 up front. Crucially we should also get players into wide areas and actually cross the ball. We seem to do neither.

I’d certainly be tempted to give 4-4-2 a go.
