Our squad management has been poor, no doubt. I don't think it's been quite as bad as others do, some of the players haven't done what we would have hoped. Enrique takes a share of the blame for his long term move away from midfield control of matches. The squad is an odd development. In the 15-16 season, we were cruising along in all tournaments, but Enrique wasn't rotating enough. Eventually, the players hit a massive wall of physical and mental fatigue, starting with Villareal away where we went from a comfortable 2-0 lead to clinging on for a 2-2 draw, then we went over a period of losing several league games and going out of the CL. It wasn't by accident that during that league run in, when our fixtures went back to 1 a week, the performances recovered and we won the Double.
The signings over this period appeared to be decent enough IMO in parts. Umtiti has done well and should grow in the role. Turan was massively disappointing, particularly coming in and being quoted as saying he was happy to leave Atletico because he wants to run less. :S Digne was supposed to be a full back cover for either side, Gomes was Liga proven cover for midfield, Vidal started to play well when he came in before getting that injury that took him out of most of last season. Guys like Alcacer are weird signings, he doesn't do anything a cantera product couldn't also do. There have obviously been squad mistakes made. Enrique isn't the visionary that Guardiola is, thus the football isn't as advanced and at times we are basically waiting on Messi to lift the team to results. The overall team strength has deteriorated, and there has been no planning for slowly replacing Iniesta, or Alves. Sergi Roberto has done as well as he could have done, but to me he should either have been worked on as a long term replacement for Busquets, or most likely shown the door. Rakitic IMO is the only midfield signing of recent years that gives us what we need in there.
The overall signing plan has been pretty poor, so much money has been spent on players we didn't play, or barely played. Obviously someone was gettint fat cheques out of those deals.
I think there is still plenty of room in this squad to continue winning big trophies, after all it was only 1 season ago we were back to back Double winners. They need to work on blooding young players with a view of establishing them in the squad, and finding top level replacements for Ineista and Alves in the first instance.
