Barcelona officially confirmed that the team's main striker Robert Lewandowski has injured his left hamstring and will be temporarily out.

The club said Lewandowski's specific recovery time will depend on the progression of his injury. Sources revealed that the Polish striker is expected to be out for up to five weeks, which would make him unlikely to play in Barcelona's national derby against Real Madrid at the end of this month.

The 37-year-old Lewandowski missed several games at the beginning of this season due to a muscle injury and did not start for the first time until the Champions League match against Newcastle United in September. So far this season, he has played 9 official games for Barcelona and scored 4 goals.

In addition, Lewandowski played for the Polish national team during the October international match day and scored two goals, continuing his stable scoring form. However, this unexpected injury once again disrupted Barcelona's offensive deployment.

With Danny Olmo, young player Gavi and goalkeeper Marc-Andre ter Stegen also out due to injuries, the team faces the dilemma of limited firepower in the frontcourt at a crucial stage. Currently, coach Hansi Flick needs to rely on Ferran Torres, Marcus Rashford and others to replace the center position to fill the vacancy left by Lewandowski .

If Lewandowski's recovery progresses smoothly, he could return as early as after the November international break. Lewandowski has been a key player in Barcelona's attack since joining the team, scoring 33 goals last season. This injury undoubtedly adds to Barcelona's difficulties at a crucial juncture of the season.
