There has been several speculation around Antonio Rudiger transfer and he is likely to move away from the team if no new deal was offered to him. Chelsea has previously made 2 offers to him which he as rejected as he wanted a higher salary which Chelsea are not ready to pay, his current pay at Chelsea is £90,000 which he think he has not be treated well despite his performance so far. So he requested a £220,000 and Chelsea are not pleased with his offer which they have dragged to this extent. But if at all Chelsea are ready to give him an improved offer now with the UK Government sanctions against Roman Abramovich its likely not possible soon until Chelsea get a new owner.
Rudiger had been getting offer from several team all over Europe, Real Madrid has been a big admirer of him, while Paris Saint Germain and Juventus are never left out. Manchester United who are currently having defensive and they are planning on strengthening their defense line. however, Rudiger don't seem to be interested in a move to any English team as he is currently patiently waiting for Chelsea for new offer, and he has given them till the end of April and if there is no talk after then he will be open for negotiation with other clubs.
It will be very difficult for Chelsea to lose Rudiger and there is no replacement currently made but there is plan to bring in another defender but Jules Kounde has been the main man on the list.
