Bayern Munich received a significant boost on Monday as Raphaël Guerreiro returned to team training, just days ahead of their crucial Champions League semi-final second leg against Paris Saint-Germain at the Allianz Arena on Wednesday.

The 32-year-old Portuguese international, known for his versatility across the left flank and midfield, was back on the pitch with his teammates after a brief injury layoff. While his return is encouraging, it remains uncertain whether he'll be match-fit enough to feature in the squad for the high-stakes encounter.

Guerreiro has been sidelined for the past two matches—including the first leg against PSG and the Bundesliga clash with 1. FC Heidenheim—after sustaining a thigh muscle injury during Bayern's thrilling 4-3 victory over 1. FSV Mainz 05 on April 25. His absence has been felt, especially given his ability to provide both defensive stability and attacking width.

In other positive news, young midfielder Lennart Karl also participated in Monday's training session and could be in contention for a spot in the squad against the French champions. With the semi-final finely poised, every available body will be crucial for Bayern as they look to secure a place in the final.
