Newcastle United striker Demba Ba is unhappy with a reduced role at the club, according to his agent.
Ba came off the bench to score twice on Monday as the Magpies came from behind to earn a late point against Everton.
Alex Gontran, the forward's agent, wants Ba's position at the club clarified.
He told BBC Sport: "Since returning from the Africa Cup of Nations, Demba doesn't understand the management.
"If he continues to be a substitute all season, we'll look at other solutions.
"How could you put your best striker with full confidence on the left wing?"
Ba was Newcastle's top scorer in the Premier League last season with 16 goals, and has three to his name at this early stage of the new campaign.
