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 on chelseafc.com: "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.
"You can win big matches even if you're not having a good season, because it is a big match or a derby, but it is the smaller matches against difficult adversaries that you will see if you are going to be champions or not."
