According to the Daily Express, Chelsea are now leading the race to sign Antonio Rudiger.
The report claims Italian side Roma have already enquired about the Stuttgart defender with a view to a season-long loan deal, but this was immediately rebuffed, putting Chelsea on alert as a result.
Roma are apparently set to table a bid for a permanent deal, as they seek a replacement for Alessio Romagnoli.
However, Jose Mourinho is set to try and sabotage this bid for the 22-year old with a £20 million bid, as he seeks more defensive options – he substituted John Terry for the first time ever as a Chelsea manager yesterday.
Arsenal were also reportedly interested in the German international, but they have seemingly been beaten to the chase.
Rudiger, who is contracted to the Mercedes-Benz Arena club until 2017, has yet to reveal if he wishes to leave Germany this summer.
The former Borussia Dortmund youth player has made 66 appearances for Stuttgart, scoring two goals, as well as making six appearances for the German national side.
