Celtic manager Ronny Deila is reportedly keen to take Barry Douglas back to Scotland.
The full-back left the Scottish Premiership in 2013 when he moved to Polish side Lech Poznan from Dundee United.
However, although Poznan do not want to sell the 25-year-old, if they were to fail to qualify for next season's Champions League, it may force them to listen to offers, according to the Daily Record.
It is believed that the Bhoys may need to part with around £500,000 to convince the Ekstraklasa outfit to do business.
