Sporting CP midfielder William Carvalho is again being linked with a move to England.
Carvalho has long been mentioned as a target for Premier League clubs.
TMW says the Portugal international is interesting Manchester United boss Jose Mourinho, with the pair counting on Jorge Mendes as their agent.
Leicester City, Everton and Southampton all made enquiries after Carvalho, 24, last summer.
A move to United is likely to hinge on the plans of Morgan Schneiderlin, who has been linked with a January move to Everton.
