Scott, 22, had a standout 2025-26 season for the Cherries, playing 37 Premier League matches and scoring the winner in Bournemouth's 2-1 victory over Arsenal at the Emirates.
He was part of Thomas Tuchel's pre-tournament camp in Florida but was not included in the final 26-man selection.
Manchester United's interest is driven by a need to reshape their midfield following Casemiro's departure. The club have already agreed a deal for Atalanta's Ederson, expected to be finalised after the tournament, but manager Michael Carrick is seeking further reinforcement for a Champions League campaign. Manuel Ugarte's future is also uncertain, with United open to offers for the Uruguay international.
Arsenal's interest reflects Mikel Arteta's desire to add technical youth to his engine room. Fabrizio Romano has confirmed conversations have taken place with both Scott's representatives and Bournemouth about the feasibility of a move.
Bournemouth are in no rush to sell. The club have secured European football for next season and are working to tie Scott down to a new contract, though his current deal runs until 2028 and they are under no financial pressure.
Scott has previously indicated he would only leave for a Champions League club, a stance that could complicate both United and Arsenal's pursuit.
Tottenham Hotspur, where Scott is understood to be a boyhood supporter, are also following the situation. The midfielder's performances this season have kept him firmly in view of most of England's top clubs even without a World Cup berth to boost his profile further.
