The Serie A side have made an enquiry for the player, but have seen that promptly turned down. However, the Giallorossi are set to go back in regardless, needing to strengthen if they are going to catch up with Juventus domestically.
A £20 million offer could also be on the way from Stamford Bridge, with the 22-year-old a potential replacement for the ageing John Terry. At 34-years-old, Jose Mourinho is going to have to find a replacement for the former England international soon, and the Germany international could be the man for the job.
Currently in the treatment room with a knee injury, the centre-back currently has two years left on contract with Stuttgart. As a result, the Bundesliga outfit may look to cash in now before the deal starts running out.
