CELTIC boss Ronny Deila has been alerted to the fact that Millwall captain Alan Dunne will leave the club for free next month.
The Republic of Ireland left-back was linked with the Hoops during the season with the Norwegian searching for cover for Emilio Izaguirre.
Right-sided Efe Ambrose was forced to play in the problem No.3 berth on two occasions – one the shock 1-0 loss at home to St Johnstone in March – as Deila looked for options.
Dunne, 32, has spent his entire 15-year career with the Lions, but will leave now after their relegation to League One..
He has racked up well over 300 league appearances for the club since arriving from Ireland.
The versatile Dublin-born defender has a disciplinary record which may make Deila wary – he has been sent off 10 times and booked on 85 occasions!
Meanwhile Celtic chief scout David Moss is being targeted by Championship side Leeds United.
The Elland Road outfit are likely to searching for a new Sporting Director if Nicola Salerno quits the post to return to Italy.
Moss, 47, has previously been responsible for the academies at Crystal Palace and Swansea City and has worked for the Glasgow giants since 2010.
He quit playing in 2003 after spells with Partick Thistle, Falkirk, Ayr United and Dunfermline in Scotland and Swansea, Doncaster Rovers and Chesterfield across the border.
