Sunderland 2-1 Chelsea (after Extra Time)

Substitute Ki Sung-Yueng dumped Chelsea out of the Capital One Cup with a 118th-minute winner at the Stadium of Light.

The Stamford Bridge side looked to be in control after Lee Cattermole's own goal in the 46th minute. Goal-line technology helped establish the ball had crossed the line.

Some redemption for his disallowed strike for England against Germany in the 2010 World Cup finals looked to be with Frank Lampard, but this time, the strike was awarded to the Sunderland captain.

Chelsea wasted a number of chances to seal their passage into the last four and were made to pay in the 88th minute.

United States international Jozy Altidore was unable to get a clear shot on goal, but the ball dropped instead for Fabio Borini to rifle in the equaliser from a tight angle.

That goal sent the tie into extra time and Mark Schwarzer twice saved well in the additional period. Ki, who won the trophy with Swansea last season, was on hand with two minutes left to slot home the winner for former Chelsea favourite Gus Poyet's side.

Afterwards, Chelsea boss Jose Mourinho said (per The Guardian):

"

We had chances and chances and chances but not enough goals. Maybe the way to rectify it is not to concede as many goals. We lose goals and the opponents come alive. We scored against Sunderland and afterwards we had two or three more chances. If we had scored then, goodbye, but we kept the opponents alive.

We've never lost a match because we didn't play or because the opponent was stronger than us. We lost every match because we produce, we don't kill opponents, we give them life and every opponent that plays against us knows they can score a goal and change the true result.

We play sometimes very well and have fantastic chances and don't score. It's the same story that repeats.

Leicester City 1-3 Manchester City

Edin Dzeko ensured the absence of Sergio Aguero did not deflate Manchester City as he claimed two goals in the 3-1 win at Leicester City in the Capital One Cup quarter-finals.

Aleksandar Kolarov opened the scoring for City with a superb 25-yard free-kick in the eighth minute of the game.

But then Dzeko, who replaced the injured Aguero in Manuel Pellegrini's starting line-up, added a second goal four minutes before half-time from a James Milner cross.

The Bosnia international was again on hand eight minutes into the second period when he side-footed home another Milner ball from close range.

Lloyd Dyer scored a late consolation goal for the Championship side to end City's run of clean sheets in the competition, but that was the least of Pellegrini's concerns by the end of the match.

City defender Pablo Zabaleta limped out of the match with an injury, and the club will be anxiously waiting on news of the player's fitness.

Ashley Young and Patrice Evra scored second-half goals as Manchester United won 2-0 at Stoke City on Wednesday in their Capital One Cup quarter-final match at a blustery and soggy Britannia Stadium.

The match included a brief stoppage in the first half as conditions became too poor to continue play on the pitch. 

Young scored the opener in the 62nd minute and Evra added the second 16 minutes later for United, who advanced to the semi-finals to face Sunderland.

Tottenham Hotspur 1-2 West Ham United

West Ham scored twice in the final 10 minutes to topple Tottenham, 2-1, at White Hart Lane on Wednesday evening.

Tottenham had led through Emmanuel Adebayor's 67th-minute volley, but West Ham turned the match around with two strikes in five minutes.

Matthew Jarvis equalised in the 80th minute before Modibo Maiga headed in the winner five minutes later.

Spurs were playing under caretaker manager Tim Sherwood for the first time since Andre Villas-Boas' sacking earlier this week.

West Ham will play Manchester City in the semi-finals. The Hammers have won their last two matches at White Hart Lane.
