Leicester City boss Brendan Rodgers is set to upset his former Celtic fans with a transfer raid.
The Sun says Rodgers could further enrage Celtic fans by beating Borussia Dortmund to the signature of Hoops star Kieran Tierney.
The German giants have emerged as contenders for the left-back in a £25million summer deal.
They have sent staff to monitor on-loan Jeremy Toljan in every Scottish Premiership game - and Tierney has caught their eye as the next youngster who could star in the Bundesliga.
The 21-year-old will be a target for Leicester if they lose Ben Chilwell in the summer, with Manchester City among the clubs interested in the England international.
