Manchester City reached the quarter-finals of the League Cup after they finally broke down a resilient Newcastle United to win 2-0 after extra time on Wednesday, while Tottenham Hotspur needed penalties to get past Hull City.
City, who made 10 changes from the team that played Chelsea in the league on Sunday, were far from fluent but came through a testing encounter with goals from substitute Alvaro Negredo and Edin Dzeko in the first period of extra time.
Tottenham earned a late reprieve when Harry Kane made it 2-2 in extra time and then booked a place in the last eight when Hull's Ahmed Elmohamady missed his penalty to hand Spurs an 8-7 win.
It was Tottenham's first penalty shootout victory in eight attempts since they beat Peterborough in the FA Cup in 1994. Gylfi Sigurdsson had put them ahead after 16 minutes with a rocket finish before a Brad Friedel own goal ensured the tie went to extra time.
Paul McShane put Hull, who lost 1-0 to Tottenham in the Premier League on Sunday, in the box seat nine minutes into the additional period, but Kane levelled with a precise finish.
Manchester City dug deep into their near endless squad of reserves but still fielded a full side of internationals. Goalkeeper Joe Hart was one of those relegated to the bench after his error of judgement on Sunday allowed Chelsea to win at Stamford Bridge, but the wholesale changes produced a stilted first-half display.
It was Newcastle who should have been ahead at the interval with their best two chances falling to Papiss Cisse.
He first lifted an early effort over City's stand-in keeper Costel Pantilimon but wide of the post on nine minutes, before scuffing another good chance across the face of goal.
That effort was poked in by Shola Ameobi from close range but ruled out for offside.
City picked up the pace after the interval and should have won the match in normal time with James Milner scooping an effort over the bar and Negredo failing to convert a one-on-one with just over 10 minutes to play.
After Pantilimon pulled off a fantastic smothering save to deny Cisse in extra-time, City struck a killer blow when Negredo stole in front of his marker to sidefoot home a cross from Dzeko.
The Bosnian got on the scoresheet himself when he rounded the keeper to make the game safe just before the halftime interval in extra-time.
