Arsenal eye race with Man United for Porto right back

October 28, 2026Jed Dogomeo

Despite having Jurrien Timber and Ben White as established options at right back, with Cristhian Mosquera and Martin Zubimendi also capable of filling in, Arsenal are reportedly looking at another addition for that position. According to Fussball News, as relayed by Just Arsenal, the Gunners have identified FC Porto's Alberto Costa as a target.

Costa has rebuilt his reputation in Portugal following a brief and difficult stint at Juventus, and his performances for Porto have reportedly caught the eye of several of Europe's top clubs. The report states that Arsenal have been following his progress closely and have been impressed by what they have seen.

Who's out, who's back and what it means for the next two games.

What Costa offers

Costa is described as a right back who reads the game well, understanding when to push forward and when to hold his defensive position. That profile fits the demands Mikel Arteta places on his full backs, who are expected to contribute at both ends of the pitch rather than operate purely as defenders.

Arsenal already have strength in depth in that area. Timber and White have shared right back duties this season, while Mosquera and Zubimendi offer further cover when needed. Adding Costa would not address a glaring weakness so much as deepen an already competitive position, with the report suggesting he could also be viewed as a long term option.

Manchester United also interested

Arsenal are not alone in their admiration. The report states that Manchester United are also keen on Costa, setting up a potential direct battle for his signature between two of the Premier League's biggest clubs.

United are said to view right back as an area in need of strengthening, and Costa's recent form has made him an attractive target for Ruben Amorim's side as well. With both clubs reportedly in the race, how this situation develops will be worth monitoring as the season progresses.

For now, Costa remains a name to watch rather than an imminent arrival. Arsenal's interest reflects a club looking to maintain strong depth across the squad rather than one addressing a pressing need, but competition from a rival Premier League club means nothing is guaranteed if the move progresses further.
