Barcelona weighing up Diego Costa move?

Barcelona are understood to be preparing a January bid for Chelsea hotshot Diego Costa.

The Spain international joined the Blues from Atletico Madrid in 2014, and played an important role in their title winning campaign.

However, he has struggled to rediscover his first season form, and has been limited to just three goals this term.

Spanish source Don Balon now claims that the Brazilian-born forward is unsettled at Stamford Bridge, and Barca may seek to lure him back to La Liga at the earliest opportunity.

Costa scored 21 goals in all competitions for the West London giants last season.
