There was a time when Tottenham looked to have the measure of Chelsea. Not anymore. Times change. They certainly have in the lilywhite corner of north London.
Three years ago, almost to the day, a Harry Kane penalty separated these teams at the same stage of this competition. It was the third straight game in which Tottenham had beaten Chelsea. Since then, no more. Chelsea won the second leg, and progressed to the final on penalties and in eight meetings after that, Chelsea have won six and drawn two.
Worryingly for Antonio Conte, his players and employers, this was one of the easier victories in that sequence.
