Premier League giants quoted huge asking price.
Arsenal and Manchester United are interested in Valencia centre-back Nicolas Otamendi, but may be dealt a blow as his club look to raise his release clause to £60m, according to CaughtOffside.
The Argentine is widely regarded as a top talent ready to move to a bigger club, with the likes of Chelsea and Manchester City also linked with him in recent times.
However, Los Che are readying a bumper new contract for the former FC Porto man that will see him double his current wages and increase his buy-out clause.
It remains to be seen if Arsenal or United would pay that much to sign the player when other big-name defenders could be available for less.
