Spurs beat Aston Villa 4-0 in the Capital One Cup on Tuesday night thanks to a brace from Jermain Defoe and goals from Paulinho and Nacer Chadli but the boss is swiftly glancing ahead to the Premier League showdown with the Blues at White Hart Lane on Saturday.
"It changes very quickly," he said.
"That is the nature of the Premier League and the excitement that it brings.
"At the moment it is going well for us. That always gives you confidence and motivation for the games that are coming.
"Chelsea is a different proposition. It is a very difficult game."
