Premier League leaders Manchester City and current champions Chelsea have booked their spots in the FA Cup fifth round after their respective straightforward victories on Sunday evening.
Manchester City defeated English Championship outfit Cardiff City 2-0 away from home courtesy of goals from Kevin De Bruyne and Raheem Sterling.
The Citizens even had the luxury of having a Bernardo Silva strike controversially ruled out for offside.
Earlier, Chelsea also secured safe passage into the last 16 with a 3-0 win over fellow top flight side Newcastle United.
Wantaway striker Michy Batshuayi, who has been linked with clubs like Sevilla, West Ham United and Borussia Dortmund, scored two first half goals before a Marcos Alonso freekick wrapped up proceedings.
