Real Madrid are unhappy with Benfica over their valuation for Antonio Silva.

Real are in the market for a young centre-half and have placed Silva at the top of their shortlist, says Ok Diario.

Silva, inside Valdebebas, is regarded as the best young centre-half in the world.

However, Real have been taken aback as Benfica have slapped a €100m price-tag on the Portugal international and are refusing to budge.

They have already rejected an offer from PSG last summer for Silva.

The 20 year-old has contract at Benfica to 2027.
