Celtic have been made aware that Arsenal are looking at permanent deals over loans as dream return chatter over Kieran Tierney lingers.
Brendan Rodgers' side are well-stocked at left-back with Greg Taylor and Alexandro Bernabei as options but that hasn't cut rumours of the club academy product making an emotional return to work with his former boss.
Talk last month suggested that the Celtic manager was keen to bring Tierney back to Glasgow and the man himself is also reportedly ready to cut his big Gunners wages to make it a reality.
Real Sociedad are the latest club to be linked with the Scotland international, who has also been heavily touted for Newcastle. £25m is the fee that took the 26-year-old to North London in 2019 but he has fallen down the pecking order and didn't start any of their pre-season friendlies, with an exit now potentially awaiting before September.
