I don't think any of the teams mentioned have recruited significantly better than us over the past 3 seasons.
I think that a lot of people use hindsight to make judgements
You see posts on how xyz player that is having a great season could have been recruited for a fraction of what we paid Sane, Mangala, Otamendi etc.
They conveniently overlook that if we had bought those players, then at the time you would likely (IMO) have seen the same posters moaning about the club not being ambitious enough.
Hindsight is a comfortable method - you can be confident in being right
