Chelsea are raiding Champions League opponents Bayern Munich for a teenage signing.
The two giants will meet in the round of 16 next year.
And Sport1 says Chelsea have reportedly offered Bayern prospect Torben Rhein a contract starting in 2020.
The 16-year-old is one of Germany's biggest starlets having represented his country's Under-16 side on numerous occasions.
The attacking midfielder's contract Niko Kovac's side expires in summer 2021, but Chelsea are thought to already be tracking his progress.
The Blues have offered Rhein a lucrative professional contract from 2020 and want him in the first team as soon as possible.
