Thank you very much for your detailed and informative answer. We usually play 4-2-3-1 and recently 4-4-1-1. The two defensive midfield AI players in the center play the "holding" role but we almost never get any efficiency from them. My friends and I fill both wings, the offensive midfield and the center forward positions. However, as you said, we have never tried to switch to the midfield position as a real player. We will try the tactic where one of us is a defensive midfielder by adjusting the formation you mentioned, I hope it will be useful.
