Dortmund starlet Jacob Bruun Larsen is at the centre of a three-way battle between Liverpool, Manchester United and Arsenal.
The Danish forward, like team-mate Jadon Sancho, enjoyed a breakthrough season in 2018/19 and the German club will want bigger offers even to consider selling him.
Larsen, 20, made 30 appearances for Dortmund, featuring 17 starts and three goals, and earned his first senior cap for Denmark in March.
More recently Larsen showed his class at the European Under-21 Championship, scoring an excellent goal in the group stage against Serbia.
Denmark were eliminated after finishing second behind Germany, who will contest Sunday’s final against Spain.
But Larsen shone and is firmly on the radar of big English and European clubs, just as he was earlier in his career.
Dortmund snatched him from under the noses of Everton, among others, when they signed him as a 16 year old from Lyngby in 2015.
Liverpool boss Jurgen Klopp was in charge of the German club at the time. Klopp left months later to move to Anfield but retains strong contacts at his former club.
Larsen joined Dortmund when heir head of scouting was Sven Mislintat, who was appointed Arsenal’s head of recruitment in November 2017.
Mislintat made a shock exit from the Emirates in February and is now at Stuttgart.
But he is thought to have identified Larsen as a summer target for the Gunners before leaving.
