Kompany is yet to win a league match in the Belgian First Division A, suffering two draws and two defeats in his four fixtures in charge, and the 33-year-old has opted to focus on playing matters on matchday, says HLN.
"Kompany must be more a player during the match," said Davies, who was previously head of academy coaching at City before he joined Kompany's coaching staff in the summer.
"He must be able to really lead the team on the field. Of course no one doubts that he can, but it is important that he is merely one of the players during the match.
"So, together with my staff, I will take on the tactics next to the field. Because you can plan some things in advance, surprising things always happen during a match. I take that on me."
