Borussia Dortmund are worried the great form shown by loan signing Michy Batshuayi could scupper any chances of the deal becoming permanent in the summer.

The German club would love to sign Batshuayi permanently, provided it is a reasonable fee.

However, his goal scoring exploits since joining mean his current employers Chelsea could want to keep him instead.

Batshuayi already has five goals to his name, in just five games at the club.

It is the type of form that Chelsea wanted to see from their striker, and there is a chance the club would have a new manager in the summer.

It is unclear where Batshuayi's future lies.
