Did he or did he not spend over £150m in 6 windows? Regardless of where the money came from. If he wasn't backed, they wouldn't have made it available.
In response to fire sale about losing good players, they lost 2 good players. The rest was pretty much crap for them who hadn't played much or had been out of form for ages. Eg cabella who had been on loan the season the got relegated anyway, janmaat who has since come good but played 32 times across 2 seasons as a squad player due to injury, cisse who went to China after struggling to score and was at that point a 1 in 4 striker for them in 100 apps. Colocinni who was 34 and left on a free. Taylor who went to the US as wasn't good enough and bigrimana who made 25 appearances over 3 years. It wasn't a fire sale or good players.
