Felipe Anderson may reportedly leave West Ham United before Monday evening's transfer deadline.
The 27-year-old has been restricted to just a couple of cameo appearances from the bench in the Premier League so far this term.
West Ham are believed to be open to either a loan or permanent exit for Anderson, who set them back £36m just two years ago.
talkSPORT suggests that Porto have enquired about the Brazilian's availability, but time is running out to agree a deal before tonight's 11pm deadline.
United's success in getting Anderson off their books could determine whether they can generate enough funds to sign Bayer Leverkusen defender Jonathan Tah.
