Talksport understands that Barcelona are considering a shock move for Chelsea full back Branislav Ivanovic.
The La Liga giants are on the lookout for defensive reinforcements and have identified the Serbia international, who has fallen down the pecking order under Blues boss Antonio Conte, as one of their top targets.
The thirty-two year old has racked up three hundred and sixty-eight appearances in all competitions, scoring thirty-three goals.
However, he has started just six from eleven Premier League games this season and could be set to call time on his near nine year stay in the English capital.
His current deal is set to expire at the end of this season, so he would not command a particularly huge fee should a potential suitor decide to table a bid.
Chelsea travel to Middlesbrough on Sunday afternoon and can be backed at a price of 8/15 to take all three points.
