Three points clear at the top of the table with a game in hand on fierce rivals Rangers, Brendan Rodgers and Celtic are looking to wade into the January transfer window as they look to retain the Scottish Premiership for the eighth season in succession.
The Daily Record reports that the Hoops are planning on submitting a £6million bid for Atalanta right-back Timothy Castagne to replace 32-year-old defender and vice-captain Mikael Lustig, in a remarkable deal manager Rodgers will hope boosts their defence adequately.
Sweden international Lustig – about to celebrate his seventh anniversary of being a Celtic player – has his contract due to expire at the end of the season, with talks of an extension not forthcoming, and is being eyed up with a return to his home country with AIK Stockholm.
Castagne is contracted to Serie A side Atalanta under 2020, with the club having the option to extend for one year.
The 23-year-old has made close to 40 appearances for La Dea since moving from Genk last year, and recently featured in the remarkable 2-2 draw at home to undefeated and presumed Scudetto collectors Juventus, albeit in a midfield role on the opposite flank as opposed to his natural right full-back position.
The Belgium has two full international caps for country having been granted his debut in September this year – against Scotland - with his stock rising, and at £6million could well be considered a coup by Celtic to replace their long-time stalwart Lustig. Though talented, Castagne is reportedly adamant about wanting first-team football which will likely see him move away from the Italian club.
Whilst Celtic once again top the Scottish league table, Atalanta sit in ninth in Serie A.
