Borussia Dortmund have an agreement in principle with Kosta Karetsas, according to Sky Germany.
The 18-year-old and his family are said to be keen on the move, with personal terms reportedly not an issue. Talks are ongoing between Dortmund and Genk, Karetsas’s club, after they turned down an offer worth over £22million, which is still some way short of their £30million valuation of the teenager.
Top clubs across Europe, including within the Premier League, have been credited with an interest in the Greece international this year. However, it appears that Karetsas wants to join Dortmund this summer to develop further.
