Barcelona are pushing to sign Chelsea defender Andreas Christensen as his contract runs down.

Sky Italia's Gianluca di Marzio reports Christensen's future at Chelsea is uncertain after he recently changed agents.

The 25-year-old appeared set to sign a new four-year deal but talks broke down and Chelsea will now have to start negotiations from scratch.

Last month Chelsea boss Thomas Tuchel stated that there would soon be 'good news' regarding Christensen, but it failed to materialise.

The centre-back, who is currently sidelined with a back problem, has made 13 Premier League appearances for Chelsea so far this season.

Having joined Chelsea as a youth player in 2012, Christensen has proceeded to feature 146 times for the senior side.
