Villarreal are standing firm over their valuation for Pau Torres.
The Spain defender is interesting Manchester United and Real Madrid.
Sport says United must meet Villarreal's release clause for Torres, or miss out on his signing altogether.
The 24-year-old has a €65million release clause, and Villarreal won't accept an offer of less than that figure.
It has been claimed, however, that the La Liga side could consider a player plus cash offer.
