Former Liverpool star Sadio Mane was forced off with an injury for Bayern Munich just 13 days before Senegal begin their World Cup campaign.
The forward, 30, appeared to suffer a knee injury 20 minutes into Bayern's Bundesliga clash with Werder Bremen on Tuesday night. He received treatment as he sat on the turf before trudging off the pitch, with Julian Nagelsmann sending on former Manchester City winger Leroy Sane as his replacement.
The sight of Mane being withdrawn less than two weeks before the World Cup gets underway in Qatar is a major cause for concern for Senegal - and fans across the world. He is the talismanic player for his nation and played a key role in their Africa Cup of Nations triumph earlier this year.
