Why squeeze 6m? If west ham thinks he is an epl player then they should buy him at that value. This isnt a flip. This is a finish product who could last them for 4 years. They need someone who can get the job done now.
If west ham wants to be an amateur club then they should stop wasting people's time, not buy epl type of players and get demoted.
I just don't see lower table teams spending more than that on a CB, but I could be wrong. So few teams actually bought center backs in the Premier League this year its almost tough to get a "going rate" but there were a few splashes of $12M-$15M with the rest in the $4M-$6M range.
