He was, however, to be given limited opportunities to impress by the Blues, with Diego Costa and Alvaro Morata blocking his path.
With Olivier Giroud brought in to bolster Antonio Conte’s options late in the winter transfer window of 2018, Batshuayi – despite having 10 goals to his name for the campaign – was allowed to head for Germany on a short-term deal.
The 24-year-old has been quick to prove his worth with Dortmund, becoming the first man in the club’s history to plunder five goals in his opening three appearances.
Batshuayi admits that belief has been returned to his game, with Chelsea having prevented him from building up any momentum during his time in England.
“It wasn’t always easy at Chelsea. I’m now playing with a lot of confidence,” he told Sporza after bagging a brace in a 3-2 Europa League win for Dortmund over Atalanta on Thursday.
“Sitting on the bench, score a goal and then back to the bench is quite difficult to deal with for an attacker.”
Batshuayi’s loan deal does not include the option for a permanent move to be made at the end of the season.
That means he could still have a future at Chelsea, although he is giving little thought to that scenario at present.
Pressed on whether he is aware of the Blues monitoring his progress in Germany, Batshuayi added: “I don’t know if Conte was watching my game.
“They are focusing on the Premier League and have an important Champions League tie next week. I hope it turns out well for them.”
