Manchester United could face a repeat of their quest to sign Frenkie de Jong two summers ago.
The Dutchman was one of the prime targets for United in the summer that Erik ten Hag took charge.
However, De Jong was committed to staying in Barcelona and rejected the move.
According to Sport, the Red Devils may be set to bid for yet another Barca player.
This time, the Red Devils are joined by Newcastle United in pursuit of Andreas Christensen.
Barca are said to be amenable to selling, but the former Chelsea player's will is still very unclear.
