Interesting take regarding a player valuation formula. The issue with hard-coding valuation is that there will be players who make a huge leap in terms of performance, but they were on a low-paying contract. If everyone can only offer the same transfer fee, they’ll pick the best team, so all the talent will accumulate at the top of the table.One way to correct market values is to remove the transfer windows and registration windows. Straight away the buying clubs aren't held to ransom by the selling clubs as they aren't restricted by a set period with a deadline to sign and register a player.
Combined that with every player having a release fee relative to the the size of their current contract or yearly pay or some sort of percentage working. For argument sake 10 times their annual salary. The average wage of a Premier league player is approximately £60,000 - £60,000×52×10=31,200,00. Now I know there are bonuses etc. this is just an idea.
If 1Rice is on £62,000 a week, you could work it out that £62,000×52×10=£32,240,00. Which in reality is more in line to what he is actually worth than what West Ham would demand.
Sancho is reportedly on £160,000 a week, so £160,000×52×10=£83,200,00. Which I think is close enough to what it was reported that Ed offered for him.
Not an exact science and fairly basic, I'm sure the governing bodies could come up with something better and a lot more straight forward and less open to abuse and creative accountancy.
I like that teams that make stupid decisions get punished — that includes us — but also can take a loss in extreme cases and quickly resolve the problem player (Alexi Sanchez anyone?).
