Sunderland, Manchester City through to League Cup semis

London: Sunderland scored late in extra time to beat Chelsea 2-1 in the League Cup quarterfinals, while Manchester City also advanced to the last four thanks to Edin Dzeko's double at Leicester on Tuesday.

South Korea midfielder Ki Sung-yueng grabbed Sunderland's winner with two minutes left at the Stadium of Light, after Chelsea had conceded an 88th-minute equalizer by Fabio Borini to take the match to extra time.

Frank Lampard opened the scoring for Chelsea with a close-range 46th-minute strike that required the approval of goal-line technology.

Like Chelsea, City rested key players but still had enough to see off the second-tier Leicester 3-1, with Dzeko's brace adding to the opener scored by Aleksandar Kolarov.

Edin Dzeko staked a claim for a regular place in Manchester City's strikeforce in the absence of injured Sergio Aguero by scoring twice in a 3-1 win over Leicester in the League Cup quarterfinals on Tuesday.

In the night's other last-eight match, Sunderland substitute Fabio Borini scored an 88th-minute equalizer to take Chelsea into extra time at 1-1.

Like Chelsea, City rested key players but still had enough to see off the second-tier opponents, with Dzeko's brace adding to the opener scored by Aleksandar Kolarov.

Dzeko has found first-team football hard to come by in recent weeks, but could see more action over the busy Christmas period after Aguero was ruled out for a month with a calf injury.

On Wednesday, it's: Tottenham vs. West Ham; and Stoke vs. Manchester United.
