LONDON, Dec 17 (Reuters) - Edin Dzeko scored twice as free-scoring Manchester City booked their place in the League Cup semi-finals with a 3-1 win at second-tier Leicester City on Tuesday.
Dzeko made his case for a more regular starting spot in City's star-studded line-up with goals either side of halftime after Aleksandar Kolarov had given the visitors an early lead.
Lloyd Dyer grabbed a consolation for Leicester.
Sunderland's all-Premier League quarter-final against Chelsea headed into extra-time with the scores level 1-1.
Stoke City host Manchester United and managerless Tottenham Hotspur take on West Ham United in the last two quarter-finals on Wednesday.
