The Premier League's top two traded six goals on Saturday as Chelsea beat Tottenham 4-2 to progress, before Arsenal overcame Manchester City in another thrilling contest a day later.
The Sunday semi-final saw two goals disallowed in the first half as City struggled to break down Arsenal.
Sergio Aguero finally broke the deadlock on the hour-mark only for Nacho Monreal to equalise with a fine right-footed volley, with Alexis Sanchez sealing the win in extra-time to set up a London derby cup final.
