Casper Terho, who was on loan at Paderborn and gained attention during the U21 European Championship while playing for Finland, is drawing interest from Hertha BSC. The Finnish winger, who appeared in eleven games and registered one assist during his time with the German second division team, is also being targeted by Blackburn Rovers and Go Ahead Eagles. Journalist Lorenzo Lepore indicated that a transfer is expected to happen after the U21 tournament, with Hertha BSC among the three clubs currently competing for his signature.
