Borussia Dortmund 'will have to pay Chelsea £53million this summer' to make Michy Batshuayi's loan move permanent.
The Belgian striker has been a revelation since arriving in the Bundesliga back in January, scoring seven goals in his first nine Dortmund outings.
This included two goals, including a 94th minute winner, after being brought off the bench in Sunday's 3-2 home win over Eintracht Frankfurt.
According to German newspaper Bild, Dortmund will have to pay 60m euros (£53m) to sign Batshuayi on a permanent basis this summer.
