Barcelona wanted to sign Willian in 2018, but their failure to reach an agreement with Chelsea scuppered things.
The Brazil international has become one of the key players under Frank Lampard and the manager has urged the Blues to offer a new deal to the 31-year-old.
His current expires at the end of June 2020.
On November 13th, Mundo Deportivo reported the La Liga winners are ‘attentive’ to the player’s situation.
Friday’s edition of the same newspaper has an update on the South American with a title ‘Fabián and Willian, waiting for what happens’.
The Chelsea star’s versatility, coupled with his contract situation, makes him an interesting option for Barca.
Barcelona are also in the market for a new centre-back due to Gerard Piqué’s age (he’ll turn 33 next February) and Samuel Umtiti’s longstanding injury problems.
Mundo claims the Blaugrana follow Nikola Milenković, who is a regular for Fiorentina and Serbia.
Willian’s club teammate Andreas Christensen is another centre-back target. Regarding the Dane, Mundo state Barca have ‘accumulated many reports for a long time’.
