Multiple reliable new sources are reporting that Man Utd have submitted a concrete bid for Trent Alexander-Arnold. The defender remains under contract at Real Madrid, but the opening offer has opened the door for discussions between the two clubs - though it is unclear at this stage whether the current bid will be enough to tempt them to part with a prized asset. Manchester City , Bayern Munich and Chelsea may look to intervene if talks continue without resolution. Defensively, Man Utd are sitting around the league average this season, at 1.42 goals conceded per game. Someone like Trent Alexander-Arnold could keep them steady but also raise the level when it matters most. Real Madrid continue to be linked with Daniel Svensson, Eli Kroupi Jr and Leny Yoro while Man Utd are also rumoured to be tracking Anthony Gordon, Alejandro Balde Martinez and Alessandro Bastoni.
