Thing is if we have bought 3 (4 with Bolasie) going straight in then we have 3 previously first 11 players now on the bench. that is strength in depth..
I thought about that before I posted my message but we, in my opinion, have managed to buy 4 players who have gone into the side without really improving the overall squad.
Williams taking over from Stones gives us short term gain but long term it is a massive step backwards. Bolasie is a minor improvement on our present wingers, but squad wise, I don't think anyone was prioritising a winger. Gana is a great buy but we are so short in midfield we need more, Barry is another year older, McCarthy seems to be not to be part of Koeman's plans so it is one for one really. Stem replaces Howard, again an improvement but again an area where we are short.
We need another forward to play with or act as understudy to Lukaku, we need a playmaker, we need a defensive midfielder, another centre half and a goal keeper.
I make my point about the squad not being collectively improved because the glaring holes are still there.
