Borussia Dortmund are reportedly keen on Celtic’s Kieran Tierney.

According to The Scottish Sun, Borussia Dortmund are interested in snapping up Celtic left back Kieran Tierney for £25million this summer.
Tierney, 21, has become a star for Celtic since really emerging in the 2015-16 season, becoming the first-choice left back at Parkhead.
A product of the Celtic youth academy, Tierney now has more than 150 appearances to his name, and is one of the top players in Scottish football having impressed both going forward and defensively.
Celtic have managed to fend off all interest in Tierney, but a host of clubs are constantly being linked, with The Scottish Sun claiming Borussia Dortmund have joined the race.
Their interest has seemingly come somewhat inadvertently, as they have been sending staff to watch Jeremy Toljan, the full back Dortmund sent on loan to Celtic just weeks ago.
Whilst doing those checks, they have been hugely impressed with Tierney, and could now launch a summer move to challenge Leicester City and ex-Celtic boss Brendan Rodgers in a £25million move.

Dortmund, who are chasing the Bundesliga title this season, do already have Raphael Guerreiro, but adding Tierney would increase competition for places.
They may also hope that successful talks with the Bhoys just weeks ago in the Toljan deal can help them win the race, especially when it comes to trying to beat their former boss Rodgers, who walked out on the club last month.
