Antonio Rudiger scored the only goal of the game as Chelsea beat London rivals Tottenham 1-0 to seal their place in the EFL Cup final.
Thomas Tuchel’s side put themselves well on their way to Wembley by winning the first leg of the semi-final 2-0 and they finished off the job at Tottenham Hotspur Stadium on Wednesday.
Rudiger’s first-half header gave them a three-goal cushion and there was no way back for Spurs, who endured another frustrating evening as referee Andre Marriner overturned two penalty decisions he wrongly awarded to Antonio Conte’s side, while VAR also ruled out what would have been Harry Kane’s 250th goal in club football.
Chelsea will go in search of a second trophy under Tuchel when they face either Arsenal or Liverpool in the final on February 27.
Romelu Lukaku came close to increasing the European champions’ advantage when he shrugged off Ben Davies, but Pierluigi Gollini spread himself to keep out the striker’s left-foot drive.
Gollini was at fault for the opening goal 17 minutes in, though, failing to deal with a Mason Mount corner and the powerful Rudiger rose highest to head home his second goal at Tottenham this season.
Spurs hopes of pulling one back were dashed when the VAR told Marriner to change his decision after he had awarded a penalty for a foul on Pierre-Emile Hojbjerg, but Rudiger had made contact outside the box.
Marriner got it wrong again when he pointed to the spot early in the second half, the official discovering on the pitchside monitor that Kepa Arrizabalaga had made contact with the ball when he came out to deny Lucas Moura.
There was yet more frustration for Tottenham when Kane lashed home, but the England captain had strayed offside.
Play was paused late on due to a medical emergency in the crowd but, upon its resumption, Chelsea cruised through added time untroubled to take their place in the final.
What does it mean? Blues hunting more silverware as Spurs’ wait goes on
That is now 11 matches without defeat for Chelsea and Tuchel is the eighth different boss to lead an English team to the final of both major domestic competitions, and the European Cup/Champions League. Bob Paisley, Brian Clough, Alex Ferguson, Rafael Benitez, Arsene Wenger, Avram Grant and Pep Guardiola are the others to achieve that feat.
Tottenham’s 14-year wait for a trophy goes on, with the FA Cup representing their only hope of finally getting their hands on some silverware this season. Chelsea, meanwhile, have progressed from all 14 two-legged ties in cup competitions after winning the first tie.
Transfer talk no issue for Rudiger
Rudiger’s future has been the subject of speculation for months, with the Germany international only under contract until the end of the season.
The 28-year-old is reported to have held talks with other clubs, including Bayern Munich and Paris Saint-Germain, but his commitment can certainly not be called into question as he produced another commanding display. The defender has scored 10 times for Chelsea, but all of those goals have come at just three stadiums (Stamford Bridge, King Power Stadium and Tottenham Hotspur Stadium).
Gollini gamble backfires
Gollini made a good save to thwart Lukaku, one of two stops he made in the match, but the on-loan goalkeeper failed to command his area when Mount swung in a corner and he was punished by Rudiger.
Spurs fans may have been questioning why Hugo Lloris was watching on from the bench, but much of the damage had been done in the first leg.
Chelsea face a huge Premier League clash away to leaders Manchester City on Saturday, while Spurs take on fierce rivals Arsenal at home on Sunday.
