Manchester United and Arsenal are interested in Porto's 22-year-old Portuguese defender Alberto Costa.

Operativ Media reports that CaughtOffside has released information on this.

According to the source, Manchester City and PSG are also monitoring the player. Currently, none of the clubs have made an official offer, and the parties are only in the scouting phase.

One of the factors complicating the transfer is Costa's contract. Porto paid Juventus €15 million plus bonuses for the player's transfer. The contract runs until June 2030.

Costa's contract includes a €65 million release clause. Additionally, Juventus retains the right to receive 10 percent of the profit from any future sale of the player.

According to reports, Costa would not only increase competition on the right flank of Manchester United's defense but also fits the club's transfer policy of prioritizing young players.

For Arsenal, the player's tactical versatility is key. It is reported that head coach Mikel Arteta prefers defenders who can play multiple roles and participate in possession-based play.

Costa made 47 appearances for Porto in the 2025/26 season, scoring 1 goal and providing 8 assists.

Transfermarkt values the 22-year-old defender at €18 million.
