Roberto Di Matteo has confirmed Chelsea are unlikely to fine David Luiz over the defender's use of Twitter and insists the centre-back remains an important part of the plans at Stamford Bridge.
The Brazilian was earlier this week warned by club officials after revealing on the social networking site he was missing Wednesday's game against Reading with a leg injury.
Luiz then also tweeted a photo of himself on a private jet and travelling to Barcelona to watch their match against Real Madrid.
The trip, which was due to a sponsorship commitment, did little to silence reports linking the 25-year-old with a transfer to the Camp Nou and could have annoyed Chelsea.
But while Luiz has been cautioned about his use of Twitter, there is not expected to be any financial punishment and he remains integral to Di Matteo's plans.
"David went to a sponsor's event. In the modern day, football players have sponsorship deals," said the Chelsea manager ahead of Saturday's Premier League game against Newcastle United.
"As long as it doesn't affect their performance, players try to obligate those duties.
"We generally don't fine our players for tweeting, although we remind them of the responsibilities they have.
"He remains a very important player at Chelsea."
Luiz is expected to return to Chelsea's starting XI against Newcastle in place of John Terry, who injured his neck against Reading.
