it is very weard formation with extremely big hole betwen defending line and attack, i have no idea how this can work.

what i would do is i would not mind how to stop this team, because if i put like to many players in defence, i would probably not win this game.

i would mind to put some pressure on him. for example play 4-5-1 flat.

with this formation i would have strong possesion of the ball in the middle and the question is if i dominate in the middle by far, who will give the balls to his TOOO MANY attackers.

so i would try 4-5-1 flat
