Chelsea rising star Andreas Christensen on Barcelona's transfer radar (Mirror)

Andreas Christensen’s Chelsea form is being monitored by Barcelona as the Catalan giants continue their search for a top-class defender, reports The Mirror.

The Dane has established himself as a regular in Antonio Conte’s starting line-up in recent months and his performances have not gone unnoticed at the Nou Camp.

Barcelona are long-term admirers and have been keeping tabs on his progress ever since he stepped in to replace David Luiz.

Christensen still has two-and-a-half years left on his contract at Stamford Bridge and Chelsea are keen to sort out a new deal to fend off interest from other clubs.

The 21-year-old, who has been capped 14 times by Denmark, joined the Blues from Brondby in 2013.

He made his Premier League debut in April 2015, shortly before agreeing to join German side Borussia Monchengladbach on a two-season loan.

Christensen returned to south-west London in the summer and has played much of the season, benefitting from Luiz’s fall from favour and subsequent injury.
