Al Ahly coach Marcel Koller was absent from the club’s final training session ahead of their game against Smouha.
The record CAF Champions League holders will take on Smouha in an outstanding Egyptian Premier League match on Tuesday at the Cairo International Stadium.
As the team prepare for the Smouha clash, Al Ahly have confirmed Koller’s health problem and mental anguish.
The Swiss tactician has been given medical attention and is currently under a strict observation.
It is unknown whether Koller will be available for the much-anticipated clash this afternoon.
Koller’s unexpected absence has raised concerns, especially as it coincides with the team’s recent patchy results.
Al Ahly were held to a goalless draw against Enppi in their last league match and suffered a 1-0 defeat to Algeria’s Chabab Belouizdad in the CAF Champions League.
Currently sitting in third place in the league table, Al Ahly could move to the top with a win against Smouha, edging out Zamalek and Pyramids by one point, though they still have a game in hand.
