Stevan Jovetic and Jesus Navas scored their first goals for Manchester City who avenged last season's shock FA Cup final defeat by Wigan Athletic with a 5-0 victory in the League Cup third round on Tuesday.
Montenegro striker Jovetic, signed for 25 million pounds from Fiorentina in the close season, scored twice on a night when fellow Premier League heavyweights Chelsea and Tottenham Hotspur also eased into the next round.
Fernando Torres started for Chelsea and scored their first goal in a 2-0 win at League One Swindon Town while Jermain Defoe made the most of his outing at Aston Villa with a brace in a 4-0 victory.
Everton squandered a lead at Fulham for whom Darren Bent clinched a 2-1 win. In another all top-flight tie West Ham United beat Cardiff City 3-2 at Upton Park with a late winner from Ricardo Vaz Te after the visitors had battled back from 2-0 down. Manchester City's 1-0 defeat by Wigan at Wembley in May led to manager Roberto Mancini being shown the door and Chilean Manuel Pellegrini taking his place at the Etihad Stadium.
Edin Dzeko put City ahead after 33 minutes and Jovetic scored from close range to make it 2-0 on the hour.
Yaya Toure curled in a free kick for City's third before Jovetic headed his second. Spain winger Navas wrapped up the scoring as City cantered to an easy win.
Torres pounced in the 29th minute to put Chelsea aheadwhen Mata's shot was turned into his path by Swindon goalkeeper Wes Foderingham. The Spain striker then played an astute pass to Brazilian midfielder Ramires whose silky finish gave Chelsea some breathing space. Tottenham warmed up with a convincing display at Villa as they registered an eighth win in nine matches in all competitions.
