Bayern Munich are the latest club to express an interest in Celtic's teenage left-back Kieran Tierney and could bid in January.
The youngster impressed during the 3-3 draw with Manchester City in the Champions League, and it has since been revealed that Bayern scouts were in attendance at Parkhead.
City themselves were impressed and will continue to monitor his performances, but now Bayern are also said to be in the hunt and will provide strong competition.
Bayern technical director Michael Reschke is keen to snap up Europe's hottest young talents, and it would appear that Tierney is high on that list.
Tierney is happy with the Hoops, who will do all they can to keep hold of their starlet, but their resolve looks sure to be tested in the January transfer window.
