Bild claims that Manchester United is the most recent team interested in Brown, following other clubs described as 'world-class', namely Man City, Arsenal, and Real Madrid. Frankfurt has established a price of €60million (£53m / $70m) for the left-back, having learned that his performances in the Bundesliga have drawn the attention of richer clubs. It has been suggested that Brown could move for €65m (£57m / $75m) or more if a competition for his signature commences. It is considered 'very likely' that the 22-year-old will leave Frankfurt following the World Cup, particularly if he performs well for Germany at the tournament.

Manchester United are closely monitoring the progress of Eintracht Frankfurt's 22-year-old German-American left-back, Nathaniel Brown, according to sources close to the agents industry who informed CaughtOffside. The same sources indicate that Manchester City, Newcastle United, Aston Villa, and Arsenal are also tracking the player. It is believed that both Manchester City and Arsenal are considering the possibility of opening talks soon to bolster their defensive options on the left side. Brown's contract with the Bundesliga club runs until 2030, and the potential absence of a release clause could place Frankfurt in a strong negotiating position. The player currently has a market value of €22 million, according to Transfermarkt.
