The Gunners needed penalties to edge out Crystal Palace in the last eight and will now collide with the Blues in Wednesday's EFL Cup semi-final first leg at Stamford Bridge.
Manager Mikel Arteta will be hoping to repeat their previous League Cup semi-final match-up against Chelsea, when the North London side won 2-1 in 2018, courtesy of Granit Xhaka's second half strike.
Arsenal will miss defenders Riccardo Calafiori (muscle injury), Piero Hincapie (injury unknown), Cristhian Mosquera (ankle) and William Saliba (not fit / recovering from injury) meaning the Gunners' defence could be weak against their London rivals as they rotate the side.
Leandro Trossard is also a doubt for the clash after missing the FA Cup win at the weekend as Arsenal came back to beat Portsmouth thanks to a Gabriel Martinelli hat trick.
Finally, Max Dowman suffered ligament damage to his ankle during a friendly against Manchester United in the middle of December. He will be out for weeks according to Arteta but could return soon after spending time in the medical room.
The Gunners have dispatched Port Vale, Brighton & Hove Albion and Crystal Palace to progress to the final four and beating Chelsea could see them face either Manchester City or Newcastle United in the final in the hunt for silverware.
