Harry Kane scored the winning goal from the penalty spot, as Tottenham Hotspur beat Chelsea 1-0 in the Carabao Cup semi-final first leg at Wembley.
In an engrossing cup tie, Harry Kane was upended by Kepa Arrizabalaga inside the box midway through the first half.
Referee Michael Oliver awarded the penalty, after the Video Assistant Referee (VAR) intervened, following an initial call for offside.
Kane tucked the penalty away in the 27th minute, but Chelsea ended the first half on top as N’Golo Kante and Callum Hudson-Odoi hit the woodwork.
Chelsea dominated the ball in the second half, but failed to find the net as Andreas Christensen missed a fine chance at the far post.
The win gives Spurs have the advantage going into the second leg at Stamford Bridge on January 24.
