With Antonio Conte reluctant to put his faith in the 24-year-old, and with Olivier Giroud snapped up from Arsenal, Batshuayi was allowed to join Borussia Dortmund on loan in January.
An unfortunate injury brought his 2017-18 campaign to a premature conclusion, but he had netted nine times in Germany and is currently on World Cup 2018 duty.
It remains to be seen what Chelsea have planned for him, with Conte’s position continuing to be called into question, and there are several clubs waiting to see the exit door opened.
Sevilla are among those, with the Liga club’s sporting director, Joaquin Caparros, telling reporters at the unveiling of Tomas Vaclik: “For Sevilla, few footballers are out of reach.
“It is true some of them could be economically impossible, but other ways can be found to sign him.
“Everything is open, and we can’t say no because then maybe they can come and we can get them. Absolutely nothing is discarded.”
Before heading to Russia this summer, Batshuayi stated that he would only enter into discussions regarding his future once his international commitments were over.
He said: "Dortmund was a great experience for me.
"They welcomed me very warmly. I was in a good environment and you could see that on the pitch.
"It was a while since I had played so much. I can't remember being allowed to play two games in a row at Chelsea. It was good to gain confidence.
"I don't have a preference; they're two beautiful clubs. My focus is on the World Cup right now and I don't want to think about what happens afterwards."
Belgium are still chasing down World Cup glory, with a 2-1 victory over Brazil on Friday seeing them set up a semi-final showdown with France.
