surely signing Okore goes some way to shoring up the defence? we now have 4 CBs for 2 positions. I think we still have Herd right? not his best position by miles but assuming he's not in a CB pair with Lowton he can prob do a job, same goes for Lowton, so we have 4 CBs and 2 players who can cover in an emergency.
I'd expect cover/competition for Lowton and Bennet to get signed too.
As for goals from other areas of the pitch, he's grabbed Bucana and Tonev already to add to the midfield mix. So it looks to be something he's thinking about at least!
I think Okore, Bacuna and probably Herd too could cover RB so I don't see that as a priority, unless we bring in someone very young as an understudy.
