London - Lincoln City boss Danny Cowley hailed his giant-killers for bringing the "magic" back to the FA Cup on Saturday but, 24 hours later, Tottenham and Manchester United restored order to the competition.
It appeared Spurs manager Mauricio Pochettino and United boss Jose Mourinho had learnt lessons from Lincoln's shock 1-0 victory over Premier League Burnley and champions Leicester's similar loss to 10-man Millwall of the third tier.
But Pochettino was keen to end a tough week with a win following defeats to Liverpool and Belgian side Gent in the Europa League so he fielded almost a full strength side and was rewarded by a Harry Kane hat-trick in a 3-0 victory over Fulham.
Spurs will host Millwall in the quarter-finals but will be wary of the 2004 FA Cup finalists who have claimed three Premier League scalps this season already.
Mourinho, whose side beat St Etienne 3-0 in their Europa League clash last Thursday, made several changes to his line-up.
Unlike Leicester counterpart Claudio Ranieri, who made 10, it didn't backfire as United came from 1-0 down to beat Blackburn 2-1 although Mourinho had to call on veteran Swedish striker Zlatan Ibrahimovic to come off the bench to seal victory.
"You need to make as few mistakes as possible, every game in the FA Cup is like a final, there are so many results not going to the favourites. We respect everyone," said Ibrahimovic.
Mourinho, who will relish the chance to put one over his former employers when United travel to Chelsea for the quarter-finals, said he was fortunate his players had shown the right attitude otherwise they might also be out.
"Their approach was brave, strong. They had real competitors and if we didn't have the right attitude from everybody we would be in real trouble," said Mourinho.
'Galvanised our football club'
United's neighbours Manchester City face a troublesome replay, and an unwanted extra fixture as they battle to claw back the eight-point deficit to league leaders Chelsea, after a goalless draw with Huddersfield of the Championship. The winners will travel to Middlesbrough.
Lincoln's fellow non-league side Sutton will be hoping to round off a weekend of shocks on Monday against an Arsenal side still reeling from the 5-1 reverse they suffered at the hands of Bayern Munich in the Champions League.
Lincoln, who had already beaten Ipswich and Brighton from the Championship, are the first non-league club since Queen's Park Rangers in 1914 to reach the quarter finals.
Many Premier League and Championship sides now field weakened teams in domestic cup competitions leading to accusations of disrespecting the world's oldest senior football knockout tournament.
"I think maybe we've brought some of the magic back," said Cowley, whose team face a trip to either Sutton or Arsenal in the last eight.
"It is a brilliant cup competition. Whoever says the FA Cup is dead hasn't lived in Lincoln for the last six to eight weeks. And it has galvanised our football club."
Leicester boss Ranieri, FIFA's coach of the year for his Premier League upset last year, was angry and frustrated after seeing his relegation-threatened side collapse again.
"I want to speak again with the players and say we have to fight every match," said the Italian.
"'Who wants to fight? Tell me'. I need the soldiers, I need the gladiators, because Millwall, with 10 players, showed they are fantastic gladiators."
