Erik ten Hag wants to bring in a new right-back over the summer transfer window to bolster his options.
Aaron Wan-Bissaka has appeared to have dislodged Dalot in the starting eleven for the Red Devils and has started the last three games.
Ten Hag is in favour of holding on to Wan-Bissaka and that has thrown Dalot’s future at Old Trafford into some doubt.
And it has been claimed that Barcelona are amongst the clubs who have been keeping close tabs on him ahead of the summer.
The Catalan giants want a new right-back amidst talk of Jules Kounde wanting to leave the club in the coming months.
Dalot is a player they like and the club are closely following his situation at Manchester United at the moment.
Transfer plans are on hold at Old Trafford due to the takeover situation but Dalot is a player that could become available.
Borussia Dortmund, Juventus, AC Milan, Roma and Atletico Madrid are also interested in the Manchester United right-back.
