Manchester United are reportedly exploring potential transfer opportunities ahead of the January window, with Manchester City defender Rayan Ait-Nouri and Bayern Munich youngster Lennart Karl among the players linked with the club.

Ait-Nouri, who joined Manchester City, has reportedly attracted interest from United, with the defender said to be open to crossing the Manchester divide in the January transfer window.

The potential move would see the Algerian international switch from City to their local rivals, although no agreement has been confirmed.

United have also reportedly contacted the representatives of Karl as they assess options for strengthening their squad.

The 18-year-old Bayern Munich midfielder has attracted attention following his emergence at the German club, with United understood to be monitoring his development.

Meanwhile, former Manchester United midfielder David Beckham has received backing as a potential future owner of the club, amid continuing discussions about its ownership structure.

The transfer developments come as United continue to face questions about their sporting direction, with head coach Michael Carrick's position reportedly under scrutiny following a difficult run of results.

The club's hierarchy is said to be considering alternative managerial options, with Newcastle United manager Eddie Howe and Julian Nagelsmann among the names linked with a possible replacement.

However, the reported transfer interests remain speculative, with no confirmed agreements or completed signings announced.
