Chelsea have made a £23m bid for Romadefender Antonio Rudiger, reports Il Tempoin Italy.
The Germany international signed for Roma earlier this week, making his loan move from Stuttgart permanent.
But a number of reports in Italy claim it will only be stop-gap for Rudiger, with Liverpool, Chelsea, Paris Saint-Germain and Juventus all interested.
For Roma's part, they would stand to make a considerable profit from the transaction, having paid around £8m to sign Rudiger permanently.
