Any thoughts?

4-4-2nd, 4-5-1v

I tried it this season and it failed. I drew and lost many games with it. I seriously doubt that Top Eleven works well for 4-2-3-1, unless your players are vastly superior to the opposition.

You should probably use the closest thing to it, which is 4-5-1. The game seems to handle that much better.
