If we can trust the BBC formations information, it does feel like 4-2-3-1 is more popular than 3-5-2 these days. By playing two genuine full backs, it would hopefully redress the attack/defence imbalance we currently have by playing two wingers as wing backs.
If I had to sum up our strengths and weaknesses in one stat, it’s this one: We outscored everyone in the division other than the three promoted teams; we conceded more goals than everyone else in the division.
