Jose Mourinho has said he is convinced that his side will qualify for the knockout stages of the Champions League, and believes they will finish in first place.
Chelsea currently sit third in Group G, one point behind Wednesday's opponents Dynamo Kiev and three adrift of Porto, who currently top the standings.
The match coincides with an alarming run of form which has seen Chelsea win only one of their last eight games in all competitions, leaving them languishing in 15th position in the Premier League and out of the League Cup.
Speaking to reporters at his pre-match press conference, as shown on the club's official website, Mourinho was in a pretty bullish mood, saying his side will qualify.
He said: "I think Chelsea will finish first in this group and if we don't finish first,then second. I am completely convinced we are going to qualify, and I think first.
"Even the match tomorrow is not a must win, it's a must not lose but it's not a must win. Our situation in the Champions League is not phenomenal, it's a normal situation."
Given the side's current predicament, there is a lot of speculation suggesting that Mourinho could be the next manager to leave the club, but having signed a four-year contract in the summer, he believes he will be given the necessary time to turn around the side's fortunes.
He also said the side are responding to his methods and nobody has said they are unhappy with the way the side is playing, and that he hasn't lost any confidence.
He also hit out at reports that a player allegedly said they would rather lose than win for the manager, saying: "I think it's a very sad accusation because you are accusing a player or more than one player... you are accusing them of dishonesty. If I accuse you to be a dishonest journalist I think you'd be very upset and you'd probably take legal action. So I think it's a question for the players, not me."
Crucially, the Portuguese coach feels that he knows the reasons for the side's dramatic slide, saying it has been a combination of factors.
He went on: "Everything is football related, we don't want to blame social and political problems in some corner of the club. We don't bring these aspects to football problems. Everything is football related of course."
"One reason would be easy to fix. It's not one reason, it's a combination of factors and I don't want to say any more."
Ahead of tomorrow night's game, Mourinho reported that Falcao will be sidelined 'for a few weeks' with a muscular injury.
