Jose Mourinho will not allow David Luiz to leave the club in the January transfer window, reports French newspaper Le10Sport.
Luiz has fallen down the pecking order at Chelsea this season thanks, in part, to John Terry's resurgence in form.
After making just five appearances in the Premier League so far, Barcelona were rumoured to be ready to give Luiz an escape route from Stamford Bridge.
Luiz himself is keen to start playing regularly, knowing a season on the bench could see him fall out of contention for Brazil's World Cup squad next summer.
But it seems Luiz will have to settle for a bit-part role at least until the end of the season as Mourinho is unwilling to part with the 26-year-old half way through a Premier League campaign.
Owing to a lack of alternatives, Mourinho wants to keep his current squad intact as they try to chase down Arsenal at the summit of the Premier League.
However, according to the French daily, Mourinho would be willing to let Luiz go in June, as he would be more confident of sealing the signature of a worthy replacement.
After a season on the bench, a summer move may come too late for the Brazilian international, who is looking to make the 23-man Selecao squad.
Barcelona remain keen on the defender despite being scared off by Chelsea's £50m asking price in the summer.
They are continuing to look for a replacement to the ageing Carles Puyol and see Luiz as an attractive option.
