Chelsea manager Jose Mourinho has said that he will wait for Diego Costa and Pedro to come through training and a fitness test before making them available for Saturday lunchtime's Premier League clash with Liverpool.
Costa was substituted during the side's League Cup tie with Stoke City in the week with a rib injury, while Pedro has missed a couple of the most recent games because of a knock.
This weekend, Chelsea will try and end a poor run of form which has seen them win only once in their last seven outings, and Mourinho has said that this weekend's opponents have replaced one top manager in Brendan Rodgers with another in Jurgen Klopp - someone he regards as one of the best coaches in Europe.
He told a press conference, as broadcast on the official Chelsea website: "They were a good team, they are a good team. They had good players, they have good players. They had a very good manager, they have a new very good manager. I think things are the same. They changed some details, obviously.
"When you change a top manager for a top manager the level is high, they know what to do."
Mourinho said that he has a good relationship with Klopp, but he wouldn't be drawn on comparisons between Klopp's last season at Borussia Dortmund and the situation his Chelsea side are currently going through.
Klopp's Dortmund side had an atrocious start to last season, which saw them in the relegation zone at the halfway point, but they managed to recover to seventh place and reach the German Cup final.
The Chelsea boss said Saturday's game is a must win 'like every game' in his career, but when asked if he could secure Champions League qualification for the side this season, he said he could offer no guarantees, with the Blues currently nine points adrift of the top four after 10 games.
Instead he drew comparisons with other high profile sides who failed to make it into the competition in recent years: "Liverpool is a big club, Man United is a super big club and last season Liverpool win nothing and didn't qualify for Champions League and they're still a big club. Two years ago Manchester United didn't qualify for the Champions League, not even the Europa League and they're still a monster club. That's football."
