Chelsea manager Jose Mourinho accepts his side's unbeaten run will not last forever, but believes the 2-1 victory at Liverpool on Saturday has only reinforced their position as Premier League title contenders.
Goals from Gary Cahill and Diego Costa, with his 10th of the season, saw the Stamford Bridge club recover from Emre Can's opener for the Reds to record a comeback win at Anfield.
The victory made it 11 league games unbeaten for the Blues' since the start of the season and consolidated their position at the top of the table, but Mourinho cannot see his team emulating Arsenal's 'Invincibles' side from 2003-04.
"I think it is possible to be champion -- before the season started we considered ourselves contenders but in modern football, especially in the Premier League, I don't believe in an unbeaten run," the Portuguese told his postgame news conference.
"It is a good start and I believe my team can keep this stability. One day we will lose and the next game we will win again and one day we will play badly because it is the nature of the game but we will recover the quality of our game.
"I know that the negative moment will arrive, the defeat will arrive, and we are prepared for that. At this moment we are a happy camp. One day the defeat arrives and when it does we will be the same."
Brendan Rodgers felt his side deserved a draw from the match after Steven Gerrard's late shot appeared to hit the arm of Gary Cahill in the penalty area, though Mourinho was relieved that goal-line technology came into play to assist in awarding Cahill the equalising goal.
"I didn't know it was a goal,'' he said of Cahill's effort. "Goal-line technology is simple. It costs money but it is simple. You don't have to stop the game, it is a decision in seconds. The truth is what everyone wants.
"Everyone knows it was a true goal and I think this is fantastic for us as professionals, for the crowd and the referee because without goalline technology it is difficult for them to make a decision.
"It [technology] is more complicated in the game itself. In Maribor [on Wednesday] they had one referee two metres from the goal and there is a clear penalty and no-one gives it so even with an additional referee is it difficult.
"So anything which helped them to be better -- they want to be perfect -- I think is welcome."
