Brendan Rodgers has admitted he must help Moussa Dembele get his head right if the striker is ever to return to his marauding best for Celtic.
The Parkhead boss, speaking after he kept the striker benched for a 5-0 William Hill Scottish Cup win over Brechin, said that multi-million-pound transfer enquiries made to Celtic have affected the star.
Crystal Palace and Brighton have registered an interest in Dembele but not yet followed up with concrete bids for the Frenchman.
Everton are also understood to be weighing up a move for the France Under 21 international.
