Sunderland striker Danny Graham is top of new Celtic manager Brendan Rodgers' wishlist according to reports.
The former Swansea City and Liverpool manager was appointed the new manager at Parkhead earlier this week and has immediately set about drawing up a list of summer transfer targets.
Graham, who spent the second half of the season on loan at Championship side Blackburn Rovers, is out of contract at the Stadium of Light this summer.
The 30-year-old frontman is surplus to requirements on Wearside and will be leaving.
And Scottish champions Celtic appear to have stolen a march on those clubs interested in securing his services, with Rovers and North West neighbours Wigan Athletic and Preston North End also tracking him.
Rodgers managed Graham during his time in charge at the Liberty Stadium, the pair also enjoyed success at Watford before Rodgers signed him for Swansea for £3.5million.
His time at Sunderland has been a major disappointment though, with Graham netting just once in 41 appearances after arriving in a £5million move from Swansea three years ago.
A haul of seven goals in 18 games at Blackburn Rovers in the second half of last season has sparked an interest in several potential new clubs but Graham would have to take a pay cut if he moved to Scotland.
Brining in a new striker is a priority for Celtic following the likely departures of Carlton Cole and Stefan Scepovic.
