Chelsea are reportedly interested in signing Harry Maguire from Manchester United.
Following the departures of Andreas Christensen and Antonio Rudiger this summer, Chelsea have been busy strengthening their defence.
Kalidou Koulibaly and Marc Cucurella have joined the club, but the Blues are still keen to sign another defender before the transfer window closes.
They have been strongly linked with Leicester City's Wesley Fofana, while they are reportedly weighing up a surprise move for Maguire.
According to the Daily Mail, Chelsea have made an enquiry about the availability of Maguire, whose place in the United side is currently under question.
The Blues are proposing a deal that would see Christian Pulisic move in the opposite direction with the Red Devils believed to be interested in the United States international.
The centre-back started the 2-1 defeat to Brighton & Hove Albion and the 4-0 loss to Brentford, and the report suggests that Erik ten Hag is considering Maguire's place in the side ahead of Monday's encounter against Liverpool. body check tags ::
