Before looking at the round four draw in full, here's a look back at the best of the round three action.
Third round action
It was Aston Villa's youngsters who made the headlines on Friday night as a result of a Covid-19 outbreak at the Villa training ground. They lined up against a strong Liverpool side but 17-year-old Louie Barry put his name up in lights when he equalised for Villa just before the break.
Liverpool proved to be too strong for their opponents, goals from Sadio Mane, Georginio Wijnaldum and Mohamed Salah secured a 4-1 and Liverpool's place in round four.
On Saturday, National League North side Chorley caused the first upset of the weekend beating Championship Derby County 2-0. Like Villa, Derby had selection problems with most of their senior squad in self-isolation meaning their youngsters were sent to the north-west to play the game. Goals from Connor Hall and Mike Calveley earned the non-league side the win.
Crawley will be joined by fellow League Two side Mansfield Town in the hat, the only sides from the fourth tier left in the competition.
Finally, the eyes of the nation were on Merseyside on Sunday evening as Premier League Tottenham Hotspur were in town to take on eighth tier Marine, 160 places below them in the footballing pyramid. Spurs put on a professional display winning by five goals to nil, which included a 13-minute hat-trick from Brazillian forward Carlos Vinicius and a first senior goal for Alfie Devine.
The final tie of the round is yet to be settled with Stockport County taking on West Ham United following the draw.
