Barcelona chase David Luiz?

Barcelona are reportedly planning a summer move for Chelsea defender David Luiz.

The Spanish club are thought to be keen on boosting their backline ahead of the next campaign.

Barca coach Tito Vilanova is now understood to have named 25-year-old Luiz as his main target for the new season, according to the Daily Star.

The Brazilian international moved to Stamford Bridge from Benfica in January 2011 for around £22m.
