That's a tough one ... I don't think that anybody can turn it around from 0:4 down. I mean if I were him I'd play it defensive with counter-attacks and there's no way you can score 4 without getting at least one.

Best you can do is something close to the Hexagon, but adjusted against his attack - 3N-1DML-2(MC)-2W-2. Hard attacking, down both flanks, own half, normal tackling, mixed passes, man-on-man marking, no counter and no offside trap. And you know ... hope for the best, but I don't think you stand a big chance.
