Former Aston Villa defender Shaun Teale believes his old team can continue juggling competitions.
Many fans are concerned about how the Midlands club will cope with both the Premier League and in the Europa Conference League.
While they are in contention for a Champions League spot in the league so far, injuries are piling up for Unai Emery's men.
"The chances are high," Teale said of winning the Conference League, per Birmingham Live.
"The problem is the demands of the Premier League, it's a very difficult league.
"Emery cannot rely on the strongest squad in every match. He has to rotate, which is a big problem. It will look like this until the decisive matches in Europe, although on Thursday he will not try anything because he needs to be sure that he will win.
"I think there will be eight basic players from the starting eleven, who mainly play in the Premier League. The coach will allow slightly older players to rest, although a lot will depend on the players' fitness."
