Our entire backline have issues defending tbf.
They need more help from the midfielders. If we're going for this 3box3 setup then the 2 at the bottom need to be able to shift. Nobody seems to cover the gaps. The Doctor mentioned it but despite Winks and Soumare being largely decent for us this season, perhaps there's an issue playing them together, because they don't both seem to provide either enough defensive cover or enough attacking impetus. I'm not really sold on the benefits of the 3box3 system when the fullback becomes a part of that front 3.
