Manchester United know the price for Benfica defender David Luiz.

The Daily Mail says Benfica are holding out for £25million for United target Luiz.

The English giants, along with Chelsea, have both scouted the 6ft 1in centre back, who can also play at left back.

But with Real Madrid, Barcelona and Inter Milan also on the 22-year-old's trail, Benfica are seeking a bumper fee.

Luiz has yet to break into the Brazil side, but was a regular for the Under 20s and has formed an impressive partnership in Portugal with his compatriot Luisao.

United have tracked him after another season in which Rio Ferdinand and Nemanja Vidic missed games because of injuries.
