We can't be wedded to one formation, be that 4-2-3-1 or 3-5-2 (or as I see it, 3-4-1-2), without the tactical flexibility this year, we would have slipped down the table.
We have the same issue with both formations; we don't have the right players to provide width and creativity;
4-2-3-1, we simply don't have the quality at RW or the depth at LW, one injury, and we have had to change formation
3-4-1-2, we don't have a natural left-footed attacking player. Atalanta have shown how attacking this can be done right, currently top scorers in Serie A with 79 goals
