This is something I've noticed and it's a really interesting pattern.The first transfer here in the list of all time record signings that was definitely a success is number 16 - Gareth Bale: Transfer records
It’s probable that Rice and Bellingham will also turn out to be successes. That’s 3 players in the top 16? It’s an unbelievably bad return in spending big.
I wonder if there's a mental aspect of being associated with such a huge fee. Maybe you just need to be a mental-freak like Bellingham or CR7 to shut out the noise, they can't all be crap players.
It's partly why I'm fine with Spurs' strategy to focus more on that £30-60m range for our "big" signings. They seem to have a higher hit rate. Not to mention our larger outlays over the years have largely been flops (Ndombele, Richy, Sissoko, Lamela, Gio, Sanchez... all the way back to Rebrov).
