Chelsea are looking to reach the FA Cup final for the fifth time in six years - with Luton Town up next in the last-16 of the competition.
The fifth-round affair, which kicks off at 7.15pm GMT today, is available to watch for free to viewers in the UK.
Last season saw the two teams meet for the first time since 1994, in a fourth-round tie at Stamford Bridge which the Blues won 3-1.
Going into this clash, Luton are on serious form in the Championship and have put together a genuine play-off push by winning six of their last seven games in all competitions.
Chelsea, meanwhile, are looking to reignite their impressive form in cup competitions by bouncing back from the Carabao Cup final defeat to Liverpool at Wembley on Sunday.
