My opinion is that Bruce has an unbalanced side, and this is largely not his fault. It must be very difficult when you have only one midfielder that is capable of playing a defensive role to cover the centre-backs, I imagine that's why he's had to so many differing formations to try and adapt to that. The other issue is that apart from Hutton, the whole team is completely new to the club, we all know it takes a long while for understanding and chemistry to develop. Whenever I've watched Bruce reflect on games he's always spoken negatively about our tendency to get "drawn into the long ball", so I can't imagine this is how he pictures us playing long-term.
We have the players (minus one more CDM), we have the manager, the chairman, the facilities and the support....It's going to take a proper pre-season to get everything into place rather than trying to improvise as we go. I know supporting Aston Villa has lacked all kinds of logic over the last half decade, but all the pieces are in place.
