I don't think we have made bad signings, we just haven't signed the players needed for them to excel. Firstly, Keane was our best CB up until around the Sunderland game, when it appears he got an injury that we ignored resulting in his hospitalization (absolute madness). However, the lad needs a settled back 4.
Klassen has come from an Ajax team where players moved around him, he got into space and he played a very simple game. Now he might not ever cut in the prem, but the poor lad has the most narrow, pedestrian side playing around him. I would like to see him given a run of games in a side with pace and movement. It might work, it might not.
Similar for Sigurdsson, he aint going to provide assets if we haven't got a striker.
Rooney is trying to do too much but we'd be [Poor language removed] without his goals.
Sandro was always going to take time to adjust but out of all of our signings he is the one I struggle to most to see fit in...even with new signings to balance the squad.
It is difficult enough for any new player to come into a new side, especially a new league but add in the fact we have terrible unbalanced squad, with a manager changing formation every week it is only even harder.
It is also criminal we haven't signed a back up LB or another CB.
