Chelsea boss Jose Mourinho believes there are four teams who are all in with a chance of winning the Premier League this season.
Mourinho's side currently lead the way from Arsenal at the top of the table after a fascinating weekend of action.
The Gunners went down 5-1 to Liverpool who are in fourth place, while Manchester City failed to score for the second game running as they were held to a 0-0 draw by Norwich.
Six points separate Chelsea at the top from Liverpool in the final Champions League qualification spot, and Mourinho believes the Anfield based side are still in the title hunt along with Arsenal and Manchester City.
"I think all the top four can win the title," he told reporters.
They [Liverpool] have a very young team to develop, the manager is very good, and the fact they don't play Champions League is very important for them," the Special One said.
"Liverpool only plays one match a week and that makes a real difference when it comes to March, April, beginning of May.
"The difference between first and fourth is six points. Everybody is in the race, everybody has an influence in the race, every team is fighting for points, every team is taking points from the big teams.
"This is the moment when the people lowest in the table feel the heat, and they feel they need to win matches. You saw what West Ham did to us, what Fulham did to United, what Norwich did to [Manchester] City - this is the reality of this league, every match is very difficult."
Mourinho has been keen to play down his Chelsea side's chances of wining the title, despite their victory over Manchester City at the Etihad Stadium a week ago.
They backed up that win with a comprehensive 3-0 victory over Newcastle on Saturday, but the Portuguese still denies that his side can win the title this season.
"I expect the team to be better, I expect the players to be better, the younger ones to evolve," he said when quizzed about his team's chances this term.
"I expect the older ones to be stable in their performance, I expect the team to have an identity, I expect the team to have a philosophy of playing and competing - and all these things are coming step by step, and for me that's the most important thing.
"Do I like to be the top of the league? Yes, I like it. I think everybody likes it! Are we going to play football to try and stay there?
"Of course we are going to. Do we think we can win tomorrow [at West Brom]? Of course we can, but it's difficult."
He continued: "Independent of mathematics, I think other teams are better placed than
"I keep saying I want to see fifth far from us because the Champions League spot is something so important. The first thing we have to do is fight for the fourth and be solid.
"This league is much more dangerous than 2012-13, so I think it's fundamental that the fifth if far from us."
