The 19-year-old was a highly sought after player this summer, but the Bundesliga and Leipzig were chosen for the Welsh international to continue and further his development.
But it hasn't gone to plan. Ampadu hasn't featured once for the German, and hasn't even made the matchday squad for their Champions League matches against Benfica and Lyon.
Ryan Giggs, manager of the Wales National Team, has revealed he is going to pay the youngster a visit to gain clarity after he admits he is concerned.
"It's a concern because Ethan is at the age now where he needs to play," Giggs said.
"I'm going to go and see Ethan after this camp because obviously the Red Bull model is an interesting one. But I will have a conversation about his progress.
"He’s had a few problems there injury-wise, nothing serious but little aches and pains. The last few camps he’s looked so much better in training. He is such a talent it’s hard to ignore. But it’s very difficult for him to play 90 minutes and back-to-back games, because he’s not had the minutes."
"I had a number of conversations last year with Frank when he was at Derby, because Harry Wilson and Tom Lawrence were there.
"I am in touch with Ethan quite regularly, but I've not felt the need to speak to anyone at Chelsea yet.
"You've seen the likes of Jadon Sancho who have done well abroad so we've seen it work. It's a good thing but they have got to play."
Chelsea will be considering calling Ethan Ampadu back in January, as lack of time game time especially with the young talent coming through at Stamford Bridge could leave him behind, and potentially out of the equation for good.
