London: Record signing Kevin De Bruyne scored again as Manchester City crushed Sunderland 4-1 to reach the League Cup fourth round on Tuesday, but Swansea City fell to second-tier Hull City.
Manchester City`s perfect start to the Premier League season was abruptly ended by a 2-1 loss at home to West Ham United at the weekend, but Manuel Pellegrini`s team bounced back in style at the Stadium of Light.
They were 4-0 up inside 36 minutes through a ninth-minute Sergio Aguero penalty, De Bruyne`s second goal for the club, an own goal by Sunderland goalkeeper Vito Mannone and a neat finish by Raheem Sterling.
"We played well, especially in the first half," said Pellegrini, whose side also lost 2-1 at home to Juventus in their Champions League opener.
"Maybe in the second half, winning 4-0, we stopped our pace a little bit, but I am pleased because we started this game after two important defeats in the Champions League and Premier League.
"It was important to continue in this cup and it was important to try to win from the first minute. We scored four beautiful goals."
