Chelsea goalkeeper Thibaut Courtois has played down the title implications of Saturday's Premier League clash at Manchester City.
The Belgium goalkeeper believes the Blues must show their ruthless streak in the fixtures which follow the City clash, against West Brom, Sunderland, Crystal Palace, Bournemouth and Stoke.
Chelsea's win over Tottenham on Saturday was their seventh successive Premier League victory. The run has led many to suggest the title could be between the Blues and Pep Guardiola's City, who are one point behind Antonio Conte's leaders and level on points with second-placed Liverpool.
Courtois said: "Now we are going to Man City to try and get another result, and then after it the next away games are at Sunderland and Crystal Palace, and it is games like those that decide if you are going to be champions or not."
Meanwhile, Graeme Souness fears 'scary' Chelsea could be Liverpool's biggest title threat.
Souness has been hugely impressed with his old club's start to the season. They currently lie second, a point behind leaders Chelsea.
"To start picking a winner now is really hard. But of the candidates, Chelsea look scary to me," he said.
"They don't have to have all of the ball to win games. Liverpool do, Manchester City do, Arsenal do. Chelsea play in a pragmatic way, they are hard to beat."
