Borussia Dortmund chief Michael Zorc admits they face competition in keeping hold of on-loan Chelsea striker Michy Batshuayi.

Since sealing a six-month loan move to Dortmund from Chelsea in January, Batshuayi has netted five goals in five appearances - two on his debut against Cologne, a goal on his home debut against Hamburg and a brace to help the German side come from behind and beat Atalanta in the Europa League recently.

Zorc concedes other teams are now interested in signing the striker this summer.

"The situation hasn't changed since his signing, and certainly not to our advantage," Zorc told Kicker.

"He has become even more interesting to others."
