100% agree.
At some point we would have had to move on from Grimes and his way of playing (or at least his role in our team, which was consistent under a few managers), and although it would be painful (as it was in the initial game/s), then LOB comes in on big money and shows what is possible. The change of manager and formation all coming at a similar time is probably for the best, even though I thought it was a risk selling our Captain in the Jan window.
We need dynamism and power in midfield, and not someone who will drop back into defence and slow things down on every move. We got caught out way too often and offered very little going forward.
