Marcus Rashford fired Manchester United into the League Cup fourth round as the holders crushed Burton 4-1, while Manchester City eased through with a 2-1 win at West Bromwich Albion on Wednesday.
City and United, currently first and second in the Premier League, took contrasting routes to the last 16, where they were joined by Chelsea, Arsenal and Everton as the big guns advanced despite fielding weakened teams.
United manager Jose Mourinho made nine changes from the side that thrashed Everton on Sunday, with Rashford and Juan Mata the only survivors.
Rashford took just five minutes to open the scoring with a deft finish and the England forward struck again in the 17th minute with a powerful effort.
“If you ask me could English football survive or even be better without this competition? Maybe we would be fresher for European competition for example,” Mourinho said.
At the Hawthorns, City boss Pep Guardiola made eight changes from the 6-0 demolition of Watford, giving Yaya Toure his first start of the season, while Ilkay Gundogan, back from a serious knee injury, started for the first time since December.
It was from Gundogan’s saved shot that Leroy Sane slotted in City’s third minute opener.
Michy Batshuayi’s hat-trick helped Chelsea crush second tier Nottingham Forest 5-1 at Stamford Bridge.
Antonio Conte made nine changes from Sunday’s 0-0 draw against Arsenal, with Eden Hazard given his first start of the season after recovering from ankle surgery.
Theo Walcott sealed Arsenal’s 1-0 win over third tier Doncaster at the Emirates Stadium.
Sanchez set up the 25th minute opener, clipping a fine pass to Walcott, who controlled well before slotting home.
