The England player returned late from international duty, and Favre is prepared to drop him despite his three goals and six appearances this season.
According to a report from German media organistion, Favre has chosen to punish Sancho because he has been late for team duties before.
This is not the first time he has been dropped, having been relegated to the under-23 squad by previous manager Peter Stoger for repeatedly turning up late to training.
Now current boss Favre made it clear that Sancho has plenty of room for improvement in his attitude.
