The report claims that United's interest in Werner should be monitored over the coming weeks ahead of the January transfer window.

Sky Germany reports that Erik ten Hag's side have already enquired about Werner's availability, but no offer has been made and there have been no negotiations at this stage.

Werner - who is in Manchester this week as Leipzig face Champions League holders Man City at the Etihad - has previously been linked with a move to Real Madrid, but the LaLiga club have cooled their interest.

The 27-year-old joined Chelsea from Leipzig in July 2020 for £45m but scored just 10 Premier League goals in 56 appearances before rejoining his former club.

Since returning to the Bundesliga for £25.3m in August 2022, Werner has scored 16 goals in his first season but has only managed to score twice in 13 games this term.

Werner has not featured for Germany this season since Julian Nagelsmann took over the helm, with his last appearance for the national team coming last summer in the Nations League.

When does the January window open?

The transfer window opens on Monday January 1, 2024 and will close at 11pm on Thursday 1 February, 2024.

To ensure harmonisation with the major leagues in Europe, the closing dates were set following discussions with the EFL, DFL, Serie A, LaLiga, and LFP, who will all close their summer and winter windows on 1 September and 1 February respectively.
