comments below from M.E.N...(the lack of attacking options when fighting on 4 fronts is a "negative" impact on the squad....I see no wrong in my comment!)

Squad depth
A glance at City’s subs bench tonight will tell you why the Blues have been so keen to land a forward in this window, until attempts for Alexis Sanchez and Riyad Mahrez both failed.
They have just Brahim Diaz to change things in an attacking sense, and if they are to make progress on four trophy fronts, they are still thin on the ground.
Nearest challengers United have six forwards for three front slots, but City at the moment have three senior players for three, plus teenager Diaz.
There is a long-held myth that City have a huge squad. They don’t – all season they have been a couple of injuries away from reaching the bottom of the barrel. Now they are very close.
