LONDON (AFP) - In-form Kevin De Bruyne struck twice as Premier League leaders Manchester City overpowered Hull City 4-1 on Tuesday (Dec 1) to lead three top-flight teams into the League Cup semi-finals.
De Bruyne had scored one goal and made two in Saturday's 3-1 win over Southampton and he continued in the same vein as the 2014 winners saw off second-tier Hull, with Wilfried Bony and Kelechi Iheanacho also scoring.
Gerard Deulofeu starred as Everton won 2-0 at Middlesbrough and Stoke City beat Sheffield Wednesday 1-0 to guarantee an all-Premier League last four ahead of Liverpool's trip to Southampton on Wednesday.
City made five changes for the visit of Hull, currently fourth in the Championship, with David Silva captaining the side at the Etihad Stadium on his first start following two months out with an ankle problem.
Sergio Aguero was absent, having taken a knock in the win over Southampton, but Bony ensured that he was not missed by following in to open the scoring in the 12th minute after De Bruyne had hit the post.
Iheanacho replaced Bony in the 71st minute and got on the score-sheet nine minutes later, toeing in a cross from Raheem Sterling.
De Bruyne's brace arrived late on, the Belgium forward exploiting a defensive mistake to prod home in the 82nd minute and then sweeping a free-kick into the top-left corner three minutes from time.
Andrew Robertson tucked away an injury-time consolation for Hull.
Former Barcelona winger Deulofeu stole the show as Everton won at Championship high-fliers Middlesbrough, who had eliminated Manchester United on penalties at Old Trafford in the fourth round.
The 21-year-old Spaniard broke the deadlock in the 20th minute at the Riverside Stadium, wriggling between two defenders and shaping a low shot into the bottom-left corner from the edge of the box.
Eight minutes later he set up Everton's second goal, bamboozling Fernando Amorebieta with a flurry of step-overs and crossing for Romelu Lukaku to head in his 13th goal of the season, and sixth in five games.
Championship side Wednesday had stunned Arsenal 3-0 in the previous round, but their cup adventure came to an end at Stoke's Britannia Stadium.
Peter Crouch limped off with an apparent hamstring injury in the early stages, but his replacement, Joselu, teed up Ibrahim Afellay to volley in Stoke's opener on the half hour.
Phil Bardsley wrapped up the win with 15 minutes to play by driving home from a free-kick as Stoke reached the last four for the first time since they won the tournament in 1972.
