Manchester United and Chelsea are battling for Porto midfielder Joao Moutinho.
Diario de Noticias says both clubs will turn to Moutinho should they miss out on Tottenham playmaker Luka Modric.
New Chelsea boss Andre Villas-Boas is close to Moutinho, having revived his flagging career at Porto.
And United manager Sir Alex Ferguson spoke regularly with former No2 Carlos Queiroz about the midfielder when he was a star with Sporting Lisbon.
