Manchester United plan to bid for Sporting CP star Bruno Fernandes this week.
O Jogo says they will step up their pursuit of Fernandes by launching a £50m bid.
Fernandes has been a target for the Red Devils throughout the transfer window but now the Red Devils are ready to make their move for the Portugal international.
Sporting have been offering the 24-year-old out to perspective suitors across Europe but their financial demands have seen most clubs balk at the asking price.
Sporting have been asking for a £70m fee but United will look to test the waters with a bid falling just short.
