Valencia president Amedao Salvo has reaffirmed his determination not to lose Nicolas Otamendi.
The Argentina defender has been linked with Manchester United.
But Salvo states: "If I dared to sell Otamendi for €49 million, Peter Lim would throw me out of Valencia (laughs).
"We said we need the €50 million buyout clause to be met to talk about it.
"If he was sold to Manchester United, I think he will bring €50 million in cash. "
