Ajax refuses bid, Perez stunned: He doesnt seem to me an indispensable player?

Kenneth Perez understands very little of why Ajax did not accept Stade Renness bid on Edson Álvarez. Reportedly, the French team wanted to pay twenty million euros for the Mexican, but Ajax rejected the bid.
Álvarez came to Ajax for fifteen million euros, which could have earned five million euros from the midfielder. I find him a disturbing factor in the game at Ajax
s ball, Perez starts at the table at ESPN Football Talk. I understand that you have to have someone who can conquer a ball, but if you dont return the ball so often, you dont have to reclaim it too often.
Overmars stated a while ago that Ajax has to sell for 50 million euros to players each season. That hasnt succeeded so far, which makes Perez wondering if it is really necessary. If you have to sell – what you say yourself – and thats a player you have a bid on, then its quite plausible that youre doing that? He doesnt seem to me an indispensable player?
