Chelsea's Brazilian defender David Luiz is ready to return from injury after missing the beginning of the season with a thigh problem.
The January transfer window signing from Benfica made an immediate impact upon his move to Stamford Bridge, scoring in wins against Manchester United and Manchester City last season.
However, an injury hit pre-season restricted the 24-year-old's involvement at the start of the season, but after being named as a substitute in Brazil's draw with Ghana, Luiz is ready to return to the first team fold.
Despite going their first three Barclays Premier league games unbeaten, Chelsea have suffered defensive problems in both home wins against West Bromwich Albion and Norwich City.
Shane Long ably held off Alex to help the Baggies storm into the lead in the Blues opening home game of the season, while against Paul Lambert's Canaries, Grant Holt almost stole a point after looping the ball beyond Hilario following a defensive mix up.
Andre Villas-Boas may feel that on both occasions his side were lucky to retain their 100 percent unbeaten start to the season and will be thrilled to be able to welcome back Luiz, as well as goalkeeper Petr Cech, who has recovered from a knee injury.
The former Porto boss may even hand a first Chelsea start to transfer deadline day signing Raul Meireles following his move from Liverpool.
Luiz believes Meireles can only improve the current Chelsea squad.
"Every day we are getting better and I bet we will have success this season. We have made good signings and I think Raul Meireles can be a big player for us," he said.
"We played against each other in Portugal and he was difficult to stop. It is sensational he can increase our level on the pitch."
