I think the foundations of the system are fairly strong, we just have guys that can't execute it consistently, square pegs in round holes etc etc.Building a team around two full backs as driving force and a temperamental striker with discipline issues cost us. You've also got a midfield trio who offer very little going forward it has virtually no creativity and a management team who had no plan b or c etc.
Also you have a strong argument that the mentality of some players just isn't good enough.
The system falls down through loss of form and lack of options, hence why it worked so well in 19/20 and then fell apart after the Winter Break.
We are a good holding midfielder, box to box midfielder with an eye for goal, a right sided forward and a striker in the mould of Morelos minus the daft red cards away from a really strong and exciting squad.
If we could get those through the door and it's guys that go straight into the starting 11 with a few going out then that's half the battle.
Helander picking up a knock in training and missing the Hamilton game has highlighted his lack of regular appearances in his senior career and now that's maybe an area where we need to look at as well, but it's lower on the priorities list than the above in my opinion.
