Manchester United are interested in Porto striker Evanilson.
O Jogo says Porto have already rejected one bid but United intend to return with a fresh offer.
United's opening bid was for £55m.
Porto value the player at closer to £70m, a price that apparently scared off fellow Premier League clubs Wolves and Brighton, who enquired after Evanilson.
Porto would like to keep hold of Evanilson, whose contract runs until 2025, but O Jogo believe an improved offer from United would test their resolve.
While new manager Erik Ten Hag's main objective this summer is to sign a central midfielder - with United in negotiations with Barcelona over Frenkie de Jong - a new centre forward would ease the pressure on 37-year-old Cristiano Ronaldo.
