The Bristol Post are reporting that Celtic are interested in signing Bradley Dack from Gillingham.
The midfielder scored 15 goals for the Gills last season and has also been attracting interest from the Premier League and the English Championship.
Bristol City had two offers rejected by Gillingham in the January transfer window, with the second bid believed to be in the region of £1.8million.
The League One side are said to be holding out for £2.5million for the player.
While the Robins’ desire to land him has waned, there is said to be firm interest from Premier League side Crystal Palace, and Brendan Rodgers is also believed to be keen on bringing in a midfielder like Dack, who can provide a goal threat from midfield.
Dack made 44 appearances in all competitions last season, and in addition to his 15 goals, he provided 10 assists.
The 22-year-old has spent his entire professional career at Gillingham after failing to make the grade at Charlton Athletic.
