Bild: Guerrero has discomfort in his thigh muscles, Kompany may only have 5 defenders available for the match against Dortmund

Bayern will have a Bundesliga match against Dortmund at home this Saturday. The German media "Bild" reported that team coach Kompany is facing personnel problems in the defense. There are currently only five healthy defenders available in the team.

In the central defender position, Upamecano and Jonathan Tower are regular partners, while substitute Kim Min-jae (who has recently suffered ankle contusions and shoulder problems) has just returned from a long journey with the South Korean national team. However, Bayern's problems at the two full-back positions are more serious.

Currently, Kompany can only use Boy as the right back, while Laimer serves as the left back. The reason: the other full-backs are either injured or out of shape. A total of four players are undergoing rehabilitation training on Thursday.

The latest injury is 31-year-old Guerrero. The left back has missed team training since Monday, and he could only perform some basic training in the weight training room last week.

On Thursday morning, he resumed training on the grass on Sebena Street: he performed 40 minutes of running training, easy passing and some basic coordination exercises, he trained under the guidance of the new rehabilitation director Benjamin Sommer.

It is worth noting that Guerrero often touched his right thigh and frequently stretched the muscles in this area. So can he make it in time for the Dortmund game? Now that's highly questionable.

As for Stanisic (partial tear of the medial ligament in his right knee), it seems difficult for him to return against Dortmund. His return was originally planned, but four weeks after suffering a knee injury, the full-back has yet to return. On Thursday, he was alone with Sommer, his rehabilitation director, practicing crossing, sprinting and long runs.

The other two injured are Alphonso Davis (ruptured cruciate ligament in right knee) and Hiroyuki Ito (third metatarsal fracture). The left-back pair have been working hard on their rehabilitation for seven months since their injuries in March and are aiming to return to the squad within the year.

So in the game against Dortmund, Kompany had to rely on a very small number of defensive stars to cope. However, so far this season, Bayern's defense has been very solid, conceding only 8 goals in 10 wins. Bayern's defense will also be put to the test on Saturday when they face Dortmund's speedy forwards.
