and my answer for you is that you can prove a diamond prfectly, 4-3-1-2 or 4-3-3 ... you don't have to think in his attack, think in th eoption that you defense do it well, and think in how to attck, these 3 formations are ok in this case, and if, for some reason he score 1st you can prove these with very defensive mentality and long passing. Thats my idea.
