Chelsea boss Jose Mourinho says his side are "champions of autumn" after maintaining their four-point lead at the top of the Premier League with victory over Liverpool.
The Blues won 2-1 at Anfield on Saturday, to keep their advantage over Southampton, who defeated Leicester City 2-0.
Chelsea remain unbeaten and have dropped only two points in six matches.
"All we can say is that we are the champions of autumn," said Mourinho.
"I think we have a very good chance to win the title but I think we, Arsenal, Manchester City, Manchester United and Southampton are all still in the race."
Chelsea came from behind to beat Liverpool at Anfield, with Diego Costa scoring the winner after Gary Cahill had cancelled out Emre Can's early opener.
However, Mourinho does not believe his side can go through the whole league season unbeaten.
"Unbeaten through the season is the impossible job, I think we will lose," he added.
"In modern football, especially in the Premier League, I don't believe in an unbeaten run.
"I know that the negative moment will arrive, the defeat will arrive, and we are prepared for that."
Mourinho on Costa's fitness concerns
"He is back. Maybe the injury was good because it made him stop, and when he has to stop he had time to recover step by step.
"In this moment he is in good condition and Spain made a fantastic decision for them and for us.
"Now he has 15 days to be at the top of his game and when Spain needs him they will have a good Diego, not a bad Diego."
Mourinho on goal-line technology
"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 goal-line technology it is difficult for them to make a decision.
"So anything which helps the official to be better - they want to be perfect - I think is welcome."
Mourinho on risking Fabregas and Ramires
"Fabregas has a hamstring injury, Ramires is the same groin injury as before, but they knew for my plan it was important for them to start the game.
"Fabregas is a fantastic professional and he gambled and I gambled. He can join up with Spain but if he does he will be back.
"Maybe the team will lose them for a match or two now but they put themselves there for the team, like I am sure others will in the future because the spirit of the team is fantastic."
