The magic was great while it lasted, but now the big boys are flexing their muscles.
After an FA Cup season which has given us plenty of shocks, it feels strange that the semi finals will be exclusively reserved for the heavyweights.
Manchester City found a middle ground between their Jekyll and Hyde performances, with a professional and comfortable 2-0 win against Middlesbrough on Saturday, while Arsenal survived a nervy first half before eventually ending Lincoln City's fairytale run to the quarter finals with a 5-0 victory.
Yesterday, attention turned to the other part of North London, with Millwall aiming to make Tottenham their fourth Premier League victim in this campaign. Spurs were having other ideas, and powered to an emphatic 6-0 win at White Hart Lane, reaching the last four of the competition for the first time since 2012.
Christian Eriksen - brought on for the injured Harry Kane - fired them in front on the half hour mark, driving a perfect volley into the bottom corner. It was two shortly before the break, Son Heung-Min curling a stunning left footed shot into the top corner.
Spurs didn't let up after the break. Son grabbed his second of the game, judging Kieran Trippier's long ball to perfection and volleying past Thomas King. Dele Alli made it 4-0, before Vincent Janssen finally ended his wait for a goal from open play with a classy finish into the bottom corner. There was even time for Son to finish off his hattrick in the final minutes, the perfect response to a section of Millwall fans who directed racist chants at him.
With competition for the Champions League places fierce, Harry Kane's ankle injury was one big blot on the Spurs copybook though. Manager Mauricio Pochettino says he's trying to remain hopeful.
"After the scan we'll know how his ankle is - we're disappointed."

Chelsea or Manchester United will fill the remaining place in the last four, and whoever the winner is tonight at Stamford Bridge, we're guaranteed to get a blockbuster pair of semi finals.
If United win we could face the possibility of Manchester and North London derbies at Wembley, while a win for Chelsea would guarantee us at least one huge all-London affair, with Manchester City taking the leftovers.
Whatever the draw, the neutral fan will be a real winner.
