TA reported that Havertz will undergo surgery for his knee problems and is not expected to be out of the situation for a long time after recovery.
TA revealed that Havertz's surgery was not a major operation. Previously, Arsenal head coach Arteta said Havertz needed "more checks" to determine his return schedule.
Last season, Havertz suffered a hamstring injury in winter training camp, so he missed for several months and did not return until the last two games of the season.
