Barcelona are exploring re-signing Thiago Alcantara from Liverpool.
ESPN says Barca are in the market for an experienced midfielder in January, with La Masia graduate Thiago on the radar.
Also being considered is Arsenal midfielder Jorginho and Real Betis' Guido Rodriguez.
Joshua Kimmich has also been raised, with agents offering the Bayern Munich ace to Barca over the summer.
Barca will seek a cut-price deal given their financial issues.
