Chelsea are set to bid £35m for Roma and Germany defender Antonio Rudiger.
Blues boss Antonio Conte is interested in signing Rudiger, and has instructed scouts to watch the 23-year-old in action.
According to the Daily Mail, Chelsea are preparing a hefty bid for Rudiger but face stiff competition from the two Manchester sides, United and City.
United splashed out in the summer to sign central defender Eric Bailly but there are question marks over a second centre-back, with Chris Smalling looking particularly uncomfortable in the Red Devils’ 4-0 defeat to Chelsea at the weekend.
Manchester City also signed an expensive centre-back, but John Stones and the Etihad club have only recorded one clean sheet so far this season in the Premier League.
Conte knows Serie A from his time with Juventus and admires Rudiger, ultimately deciding against signing him in the summer after the Roma defender sustained a serious knee injury before Euro 2016. However, the defender is fit again after his injury, making a successful return to action during Roma reserves’ win over Novara where he scored and assisted.
While Roma are keen to hold onto Rudiger, a bid of £35m could persuade the Italian club to open talks over a potential sale. Chelsea have recently switched to a three man defence, and Rudiger could be a potential successor to 35-year-old John Terry, who’s stay at the club is surely coming to an end, or Gary Cahill, who’s form this season has been inconsistent.
Should Chelsea’s pursuit of Rudiger prove unsuccessful, they could turn to Burnley’s Michael Keane or Middlesbrough’s Ben Gibson as alternatives.
