Nah, long term its more important to stand firm and only accept bids that reach or are close to your valuations.
West Ham are absolutely swimming in cash, if they really wanted McTom they would of bid higher.
If your evaluations are nuts and you refuse to compromise on it, then all it achieves are having not good enough players in the payroll and getting no money from them.
It is what we have been doing for years.
Step 1: offer high salary to not that good players.
Step 2: when someone wants to buy them, put a high price on them.
Step 3: considering that no one is buying the players and their contract is expiring, extend their contract.
Step 4: the player is not that good and thus not playing much, thus the value lowers further.
Step 5: loan them in their last 1-2 years, often paying part of their salaries or sell them for far less money than we could have done before.
Step 6: complain that there is an anti-United tax that teams offer for our players less than if they were playing in other clubs.
Same might happen here, no one in their right mind would pay 40m for him and it seems that only Moyes is desperate/stupid enough to pay 30m. He won’t play much this season, then next season we will try to sell for 15-20m. Or loan him at the ridiculous hope that he will suddenly either become good enough for us, or so we can sell for more in the future, neither of which will happen.
We have seen this movie with Lingard and Henderson before.
