Chelsea scouts are in Germany to watch Roma defender Antonio Rudiger, who is due to start for Germany against England tonight, according to the Daily Mail.
The centre-back will reportedly cost Chelsea £30million if they like what they see.
Rudiger has made 27 appearances during this season.
To recall, on 19 August 2015, Serie A side Roma signed Rüdiger on loan from VfB Stuttgart for €4 million. The clubs agreed on an optional €9 million transfer fee at the end of the one-year contract. On 30 May 2016 Roma officially signed Rüdiger from VfB Stuttgart for €9 million + €0.5m bonuses in a 4-year contract.
