The Blues had taken the lead through Alvaro Morata’s first goal of 2018, after the Spaniard collected Willian’s sumptuous pass.
However, a scrappy Jamie Vardy equaliser was enough to take the game into extra time.
But it was Pedro who rose highest to head home an N’Golo Kante cross, and send Antonio Conte’s men to Wembley.
MOMENT OF THE MATCH
In a first half that was particularly stale, Willian managed to spark the tie into life. The Brazilian picked the ball up in his own half and drove away from the challenge of Ndidi. His pace and skill was electric, drawing defenders to him in a fevered state of panic. Not to be deterred, he slipped a sumptuous pass into the path of Alvaro Morata, who duly tucked away his first goal of 2018.
STAR MAN – N’GOLO KANTE
The France international very rarely delivers a perfroamnce below an 8/10, but he was particularly impressive on Sunday afternoon. Returning to a freezing cold King Power Stadium, the midfielder broke up Leicester’s rhythm superbly and was excellent at bringing the ball out from deep. And just when it seemed like he couldn’t do enough on the pitch, he also popped up with the crucial assist for Pedro.
What the managers are saying
Antonio Conte praised the character of his side and claimed Chelsea derserved to make it to the semi-finals: “I think we must be pleased with the character that we showed.
“It wasn’t easy to play against Leicester because I think they are a good team with great players and we must pay great attention, especially when we are attacking because they have very good players who attack the space and the defensive line.”
