Jose Mourinho will expect Chelsea to revive their Premier League title challenge away to London rivals West Ham United on Saturday after their recent dip in form.
Mourinho's men narrowly escaped a second successive league defeat immediately before the international break when a controversial penalty deep into stoppage time secured a 2-2 draw with West Bromwich Albion.
The debate surrounding Ramires's tumble that won the spot-kick has continued and diverted attention away from Chelsea's underwhelming display which followed an even more lacklustre effort in a defeat at Newcastle.
Now Chelsea, currently four points behind leaders Arsenal, will attempt to rediscover their form at Upton Park against a West Ham side desperate for points following a disappointing start to the season that has left them on the fringes of the relegation zone.
Blues defender David Luiz was one of the players who paid the price for the recent results, dropping out of the side for the last two matches.
Gary Cahill stepped into the team to partner John Terry in central defence, but Brazil international Luiz insists he is happy to bide his time and wait for another chance to prove his worth rather than agitate for a transfer.
"It will be like it has always been, I am never worried. I train hard and seriously every day, he (Mourinho) has his options," Luiz said.
Brazil coach Luiz Felipe Scolari meanwhile, has no concerns about the former Benfica player's lack of action at club level, insisting that it will not affect his selection for the national team.
Scolari said: "It depends on the managers and the clubs where they play if the players will be starters.
"When I call up someone for the national team, I do so based on my observations. I won't interfere in their job because I don't want any of them to interfere in my call-ups."
Chelsea striker Fernando Torres is back in contention after missing the West Brom game through injury and will challenge Samuel Eto'o for a place in Mourinho's starting line-up.
West Ham have struggled for goals this season and manager Sam Allardyce was linked with a move for Chelsea forward Demba Ba on deadline day.
A dismal defeat at Norwich last time out summed up their problems in front of goal, but Allardyce believes Ravel Morrison can provide the spark needed for his side to survive.
"Ravel's blessed with talent. We all know his ability has started to be applied in the right way," Allardyce said.
"For me, there's still a massive room for improvement. There's still better to come. There's still more I demand.
"Hopefully that will continue to improve his development and help West Ham be a better team with better results in the near future."
Allardyce is also hopeful James Collins and Joey O'Brien will recover from injury.
"To take the pressure off us all we need results. We have not achieved that so far and we need to turn the performances into results," he added.
"There is a chance to see where Chelsea's weaknesses lie after their defeats.
"But anything less than top form for all of our players would make life difficult for us.
"In terms of our goals it is not that we are not creating chances but we are not converting them.
"Our chance conversion rate is among the worst. We will have to produce the end product because creating chances will be harder against Chelsea."
