Chelsea keeper Thibaut Courtois has insisted that his side do not have the Premier League title in the bag, despite their dominant start to the season and the struggles of their rivals.
Jose Mourinho's side are unbeaten in 10 matches in the campaign and hold a four-point lead over second-placed Southampton, but are even further ahead of rivals Manchester City in third.
However, the Belgium international is adamant that he and his teammates are taking nothing for granted at this stage of the season.
"We don't have the title in the bag," Courtois told reporters. "We are working game by game. The Premier league is very difficult.
"We are trying to win with every game that is possible. But there will be a still a long way to win the title. We are working hard. Hopefully that will be enough."
Chelsea return to action in the Premier League against West Bromwich Albion at Stamford Bridge on Saturday.
