I still think £60m wasn't a bad deal given his true worth in today's market was much higher than that.
£20m will be great value in Jan.
Free would be amazing next summer.
Sure based on how are purchases escalated as the season went on, perhaps.
But if one were to step back and view it safely, I'd say Sanchez was worth about 60 to 70 Million tops.
He is 2nd level superstar ( A rung below the Messi, Neymar Suarez, Ronaldp tier), then add the fact that he is 29, so at best 2 peak years and then may 3 declining but still good years left. So again you'd rank him fee wise below rising stars like Coutihno, Dembele" Isco and Lemar ( even if he is still currently better, he won't be in 2 years). So definitely worth less than 90 million. At best 80 million
Now add the fact he has one year left... You can split his fee by half conservatively, or perhaps even 1/3.. So we are talking somewhere between a good deal at 25 million to a slighly expensive deal at 40 million.
Anything above that, knowing all the facts seem insane.
I mean put differently, David Silva is on about the same level as Sanchez, perhaps a little older, but assuming City wanted to sell him with 2 years left on his contract. How much can we get?
My guess would be 30 million tops... So why would we pay doubme that for someone with even less time on his Contract and more dependent on his Athletism?
Don't get me wrong, teams pay these exorbitant fees every now and then, but more often than not they are mistakes..
This is a function of risk and not uncertainty ( to bring my freakonomics knowledge to bare :p)... These things should be easily calculateable.
