Chelsea defender David Luiz is reportedly prepared to force a move to Barcelona should Jose Mourinho block a proposed transfer to the Catalan club.
Luiz was the subject of a £35m Barcelona bid according to reports, but the Blues rebuffed the approach.
However, the Daily Star suggests that Luiz will push for a move should Chelsea stand in his way of joining the four-time European Cup winners.
Jose Mourinho has praised the quality of Luiz in pre-season since the defender's return from the Confederations Cup, but said that he 'can improve defensively'.
Luiz arrived at Stamford Bridge from Benfica in January 2011.
