Luiz, 25, has reportedly been monitored by the Catalan-side since arriving at Chelsea from Benfica in January 2011.
The 25-year-old is an attack-minded, industrious and versatile defender, who can also operate in defensive midfield and as an auxiliary full-back in emergency scenarios.
However, David Luiz has proven to be error-prone during his time at Stamford Bridge, having been caught out on far too many occasions for the Blues.
The Brazil international has insisted that his fully focused on Chelsea amid speculation linking him with a move to the Camp Nou at the end of the season.
Nonetheless, the 25-year-old Brazilian is flattered by the speculation linking him with Barcelona.
“I’m happy that a club such as Barcelona is interested in me. They’re a team of winners and their interest is a source of pride for me,” David Luiz told The Sun.
“I’m a Chelsea player for now. I work hard every day to make people appreciate what I do.
“I try to do my job in the best way possible, wherever I am.”
Luiz has bagged four goals in 36 competitive appearances for Chelsea this season.
Long hoping Lukaku stays at West Brom
West Bromwich Albion striker Shane Long has urged strike-partner Romelu Lukaku — who is currently on loan from Chelsea FC — to return to The Hawthorns next season, Sky Sports reports.
Lukaku, 19, has already stated that he would be open to returning to West Brom next season, with Chelsea having added Newcastle United talisman Demba Ba to their squad in January.
The Belgium international has been one of the signings of the season, along with compatriot Christian Benteke (Aston Villa) and Spanish sensation Michu (Swansea City), in the English Premier League.
The pacy, powerful 19-year-old — who joined Chelsea from Belgian Pro League giants R.S.C. Anderlecht in August 2011 — has tallied 12 goals and two assists in 25 league appearances, 12 starts, for West Brom in 2012-13.
Long, who rightfully pointed out that there are plenty of strike options at Stamford Bridge, has lobbied for Lukaku to stay on at Albion beyond this season.
“Rom is still young. You look at him and can’t believe he is 19-20. He has a lot of learning to do but he wants to learn, is relishing the challenge here and it is good to play alongside him,” said Long.
“They’ve got plenty of options at Chelsea and I think he likes it here. He likes playing for the manager, he likes the lads and he finds it fun coming to training every day.
“Hopefully we can get him back next season and keep him going the way he is going.”
