Not entirely sure the squad is that unbalanced. We have plenty of options in defence now that Connolly is playing in his best position, in midfield (especially when Freck is fit and Pett fully fit), and out wide.
The Cowleys' big mistake was letting Rhead go without a replacement, although I suspect they hoped to bring in a goalscoring-type striker instead.
Toffolo we have no cover for until Coker is fit, but apart from that we have decent cover for every position bar a Walker=type striker, which every club is looking for.
They may not of course all turn out to be the players MA wants going forward - January will tell on that.
