Manchester United eye £9m Greek star midfielder Sotiris Ninis while Benfica slap £25m tag on defender David Luiz
Meanwhile, Benfica are holding out for £25million for another United target, David 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.
Chelsea have taken progress reports since the summer, when sporting director Frank Arnesen checked him out along with other Benfica stars Angel di Maria and Fabio Coentrao.
The mean Benfica defence has conceded just 14 goals in 26 league games this season.
