During the last two summer transfer windows, one of the players repeatedly appearing on Chelsea's radar was German defender Antonio Rüdiger. At first, he was at Stuttgart, then he moved on loan to AS Roma, who then picked up the buy option on his contract this summer, possibly with a view to sell him on for a lot more.
Chelsea were reportedly close to being that interested buyer, but before a move could be done, the 23-year-old tore a ligament in his knee. He finally made his return to training this week, and so the transfer rumors have returned as well.
According to Italian newspaper Leggo, if Chelsea, or another club like Paris Saint-Germain remain interested, Rüdiger would be open to a change in scenery.
As is the case with Kurt Zouma, who's been out of service for a long time with the same injury, it's too soon to tell whether Rüdiger will be at his previous level of play once he steps back onto the pitch. But if he does, we should expect his name to continue making the rounds in the Chelsea rumour mill.
