Bundesliga side could swoop for the young international defender.
Borussia Dortmund are favourites to sign Celtic star Kieran Tierney in the summer, with the German side 3/1 to capture the 21-year-old’s signature.
The Scotland international has made over 100 appearances already for the Hoops and his performances of late have said to make the Bundesliga leaders very interested, with the likes of Jadon Sancho already flying the flag in Germany for future British stars.
Since the market has been on site, 65% of bets have gone on a move to Dortmund, which could see a deal that includes a transfer fee of £25 million.
Oddschecker spokesman George Elek: “Celtic fans will be desperate that the bookies have got it wrong, but it would be no shock to see Dortmund mine British clubs for top talent after the success of Sancho, and the young defender is another one who looks destined for the top.”
