The 31-year-old striker could be available for 10 million euros (£8.7 million), TeamTalk reported.
Manchester United head coach Erik ten Hag, on a shoestring budget, wants to bring in a striker and, ideally, a defender too.
Taremi could fit the bill as the center-forward United need to support Rasmus Hojlund.
Taremi’s contract expires at the end of the season, so Porto could look to cash in during January. A report in Italy from Inter Live, relayed by Sport Witness, says United will rival Inter for the striker who scored 31 goals in all competitions last season.
Taremi almost moved to the San Siro in the summer with AC Milan but reports suggest Porto and the player changed their terms at the last minute, forcing the Rossoneri to pull out of the deal. Porto could be ready to accept less than £10 million in the new year to avoid losing the striker for nothing next summer.
