Agreed. Hard to be critical of course, but definitely feels like a top CB really was the final piece of the the puzzle as Jose called it.
Having said that, assuming Tangana's injury isn't serious, this does mean he should get some game time in Europa, which long-term is perhaps for the best given how promising he looks.
Plus, January's only 2 and a half months away, so if our defence is still bleeding goals, you'd hope the club decide to go all in on a top CB (given it seemed to be the consensus within the club that was the key position to upgrade). Alternatively, if our CB's start to gel, a top DM to replace Sissoko/Winks would be the other 'missing piece'. But other than that, I think our squad looks extremely exciting, and no reason even without any other additions that we can't compete on all fronts (which I don't think any of us have been confident of in a while).
