Shrewsbury Town kid Ben Crompton has reportedly turned down a deal with Celtic ready to swoop.
Ange Postecoglou has stated that he is already hard at work to add to the Premiership champions squad ahead of their defence next season.
With Champions League football on the agenda, the 18-year-old could be brought into the youth set-up according to reports.
According to The Shropshire Star, the defender has turned down a new contract despite the League One side being keen to keep him at the club.
The short-term deal was turned down with Celtic having "tracked his progress" in recent months.
They note that the teenager is looking for a long-term deal rather than a short-term solution in the English lower leagues.
During his tenure, Postecoglou has brought in the likes of Johnny Kenny from Sligo Rovers as he looks to build to the future.
Crompton could join Iraq full-back Mohanad Jeahze from Swedish club Hammarby among the early arrivals this summer.
