Chelsea have a fully fit squad ahead of their trip to Premier League leaders Leicester City. Captain John Terry and Brazil midfielder Ramires were injury absentees during the 1-0 defeat to Bournemouth on 5 December while Radamel Falcao, who has not played since the 3-1 defeat to Liverpool in October, missed the club's Champions League win over Porto after returning to training at the beginning of the week.
The Blues are currently 17 points adrift of the league leaders, but under-pressure manager Jose Mourinho told a pre-match press conference on 11 December every member of his first-team squad is fit and ready for selection.
Earlier this week goalkeeper Thibaut Courtois suggested there were as many as eight players who were guilty of underperforming in a season where the club have already lost eight Premier League matches.
"I don't know it its eight players, or seven players, or six players, or five players," Mourinho said when quizzed on his goalkeeper's comments. "As a manager it is difficult for me to go in this direction. I prefer to not speak about the last month. We were miles away from our level and obviously when you have some individuals who you are waiting for performances from and you don't get them, it has an impact.
"But in the last couple of months, everyone is improving. We are going in a good direction in terms of the level of the individuals and the team consistency. We need results."
At this point in the league last year, Chelsea sat top on their way to securing the title while Leicester were two points adrift at the foot of the table. Having watched his one-time Chelsea predecessor Claudio Ranieri oversee their rise this season, Mourinho believes the Foxes must be seen as title challengers.
"Leicester win can win the title. They are doing magnificently well and we are where we awe because we are doing bad. We have the same potential as last season, the same manager, the same players, if we are where we are its cos we are underperforming. Leicester are where they are because they are doing well."
