German outlet Sport1, as quoted by Metro, is reporting that the Gunners, the Red Devils, Chelsea FC and Liverpool FC are among the teams keeping a close eye on the 20-year-old ahead of the January transfer window.
According to the same story, Havertz is expected to push for a move in the summer next year after having netted 20 goals last season.
The same article says that Premier League champions Manchester City are also interested, along with FC Barcelona and Real Madrid.
It is also claimed that Bayern Munich are targeting a move for Havertz, but Bayer Leverkusen are also likely to demand a £91m fee to sell the talented youngster.
The midfielder has already netted two goals for Leverkusen this season and he is likely to attract plenty of interest if he keeps up his current fine form.
However, the story says that Havertz is a lifelong FC Barcelona supporter, so that could make it tricky for other teams to sign him if he does indeed move away from Bayer Leverkusen next year.
