Part 1
My take on it is that you have to compare last season's squad with this season's squad. The transfers chess moves is only one part of it.
Last season's squad had - Hart, Aurier, Toby, Sissoko, Lamela, Gedson, Bale, Vini
Their replacements are - Gollini, Emerson, Romero, Skipp, Gil, John, Sessegnon, Scarlett
So everything Gary said above about guys like Romero being an upgrade on the departing Toby and the other switchws is absolutely fair. Where I worry most is that contribution we got from Bale and Vini. That isn't a slight on Sess or Scarlett either. Their time will come.
Part 2
Levy now needs to scrape together every last penny he can find and throw it all on a striker. Forget every other position on the pitch in January and go all out with a £50-100m bid for a young, hungry striker. Tell them that they are first choice and make sure they land on January 1st. If possible, go and find a second striker to bring in on loan and pay them more than they are worth.
Remove the dependency on the entitled one and then watch every other player in the squad start playing for their Chairman, MDoF and First Team Coach.
