Retired athletics star Bolt underwent a trial at Dortmund last week as the 31-year-old tested out his skills to see if he can make the jump from sprinting to football.
Batshuayi, who is spending the second half of this season on loan at the German club from Chelsea, was not present to see Bolt train as he is currently away on international duty with Belgium.
But the striker admitted he has watched videos of Bolt at Dortmund’s training base, and joked about his fear the retired athlete could replace him in the starting line-up.
“I watched the videos [of Bolt],” Batshuayi told Belgian media.
“He did nutmegs and scored a good goal. He’s a champion. He pushes himself beyond his limits every day.
“He wants to beat all the records. He’s trying to establish himself in another sport, that’s classy, I’m happy for him. But I hope he doesn’t come and take my place!”
Bolt retired from athletics after losing his world title in London last year, and has made no secret of his desire to play football.
Before going on trial at Dortmund, the 31-year-old participated in a charity match attended by Jose Mourinho – with Bolt joking that he had already spoken with the Portuguese about playing at the club he supports, Manchester United.
