What's wrong in Atletico wanting to pay less than 5m for Tiago? This is bussiness after all. And you don't expect them to pay what we (ehm, Secco) paid for him, do you?
We agreed on a 7/8M€ (not sure which was it) sign fee when we loaned the guy to them. After the loan expired, they said they weren't interested. Some weeks later they want him, but only on
THEIR TERMS. Afterwards, they agreed for 5.5/6M€. Now they want to pay even less than that.
This isn't business.
I never expected Atletico to pay 14/15M for him. But if you can't see where this is wrong, then there's nothing I can do to explain it.
