Depends of your squad abilities;
-some 3n52 formation if you want to play offensive; 352 flat, 352V, 3142, 3DC-3MC-2WAM-2ST
-3n151 as more defensive version (due no 2nd st).
Tactics: mixed passing through flanks, zonal marking, offside trap ON!, whole pitch (high) pressing, normal/hard tackling, normal mentality should work
