Imo it can all be traced back to the club letting players run down their contracts. If you can extend a player that’s great, one less spot to fill in the window. If they won’t sign you sell them and have money to buy a replacement. This is what the club should’ve done with Fabianski and Sagna. 2014 was the first of many windows that we had too many fires to fight. Our net spend skyrocketed after 2013 but instead of buying one or two top players each window like say Liverpool have done we just bought four or five average ones in each window because we had too many areas of need.
