You missed that big part of destroying the winning mentality, the leadership in the team which can't simply be replaced by transfer dealings, at least in short term.
Moyes took away Vidic, Rio, Evra with him. Giggs retiring too & frustrated with Moyes as well. Stemmed RVP our most influential attack from SAF's final season. Gave Rooney that contract and pretty much ensured Rooney getting more influence even when his performance ain't improving. Rooney is not leader. A good teammate he is, but never someone to lead a team. So the senior players hierarchy left for the incoming LVG: Rooney, Carrick, an ill Fletcher, Evans, Smalling, Young, Valencia, DDG. Beside Fletcher, pretty much every lacks leadership quality.
How Moyes gave Adnan that wage in that season, Nani that extension then not to utilize him is also baffling. Then making us look desperate & stupid by chasing impossible targets (using his credibility as a coach), while having absolute disastrous plan B if you can call Fellaini, Baines combined bids as plan.
Oh not that winning mentality argument! Chelsea were basically fighting against relegation when Mou was sacked ffs.
As far as Vidic, Rio and Evra are concerned, all three were finished and only Vidic's exit was decided during Moyes era. Evra signed a contract extension post his sacking and left a couple of weeks later. Rio was told after that season's last game that he won't be getting a new contract. Giggs was basically asked to retire by LVG so that he could become his assistant.
Everyone knew RVP wasn't a long term signing and he was already 30 by that point. As far as Rooney is concerned, he was among our best players that season and fans wanted him to get a new contract.
Adnan was being chased by PSG and other top clubs and most wanted a new contract given so as to avoid a Pogba situation. Nani's move was baffling I agree.
Our transfer window was a disaster I agree to that as well, but even Woody is to be blamed for that and not just Moyes.
Moyes wasn't the right one, no one's disputing that but all I'm saying is to blame him for our current situation is baffling. This is a list of players we've bought since he left:
Valdes, Romero, Shaw, Rojo, Blind, Bailly, Darmian, Schneiderlin, Schweinsteiger, Herrera, Pogba, Mkhi, Martial, ADM, Depay, Zlatan, Falcao.
That's 1 player for each position with a strong bench as well
To blame Moyes for our transfer disasters since then doesn't make any sense
