Birmingham City face stiff competition for Coventry striker Leon Best.
The Sunday Mercury says Celtic have joined the race for Coventry's highly-rated striker Best.
Republic of Ireland forward Best, 23, is in the final year of his contract after failing to agree new terms. He is free to leave the Ricoh Arena for just compensation in the summer.
Birmingham and Championship rivals West Brom have already sent scouts to watch him in action. But now Glasgow giants Celtic have joined the hunt for the striker.
