Biggest issue for me is that we still don't seem to have a basic system down.
Not talking about formations but rather movement patterns, both collective and individual. More than 12 months in and it's still 11 players on the field who seen to have no idea of what their teammate is going to do when he gets the ball.
Thankfully we have among the best squads in the league and a couple of players who can create something out of nothing, but we still lack a collective way of playing in possession.
Defensively it's a bit better, partly because more players are committed to defending than to attacking.
For me it points to massive training ground issues, either down to players not bothered or more likely IMO, down to a lack of quality in coaches and backroom staff. As well as Bruce not being able to create a system/tactic or to get his coaches to develop it with the players.
Or worse case scenario Bruce doesn't feel we even need those things and that it is enough to put players on the pitch and that their individual quality will do the job.
I refuse to believe he can be that naive, but if he is he needs to go asap.
