Paris (AFP) - Saracens crushed Connacht 64-6 to book the final European Cup quarter-final place on Saturday while Toulon and Ulster secured home ties in the last eight.
Champions Toulon won 15-8 at Glasgow while Ulster claimed a 22-19 success to inflict a first home defeat in this competition on Leicester in seven years.
Leinster's 36-3 thrashing of Ospreys on Friday night had left just one remaining place up for grabs in the last eight and Saracens knew that a victory would be enough for them to secure it.
But they weren't content with merely beating their Irish visitors as the 2011 English champions ran in an astonishing 11 tries, including a hat-trick from wing David Strettle, in a swashbuckling performance.
But for their missing eight conversions, the final score could have been even more humbling for the Irish province.
The only black mark on an otherwise ideal day was a wayward kicking performance from Charlie Hodgson, who managed just four successful kicks from 12 attempts.
Scottish fly-half Dan Parks opened the scoring for Connacht with a penalty on five minutes and even put the visitors back in front with a second successful kick on 21 minutes following England wing Chris Ashton's opening try in the corner for Saracens.
Hodgson put the hosts in front with a penalty, a rare successful strike from the tee, before tries from Strettle and South African hooker Schalk Brits put Saracens in control 18-6 ahead at the break.
The second half was one-way traffic as Strettle with two more, full-back Alex Goode, lock George Kruis, American Chris Wyles, substitute flanker Jackson Wray, Samoa prop James Johnston and Ashton again, capping it with his trademark swallow dive, all crossed the whitewash.
Despite the stunning nature of this victory, Saracens will be away to top seeds Ulster in the quarter-finals.
"We are not a top two or three European side but we are a top eight team," said Sarries boss Mark McCall.
"We can step up and learn from defeats at Clermont and Toulouse and can win away."
Saracens could have snatched top spot in Pool 3, and an outside shot at a home quarter-final, but Toulouse stayed in command with a 16-6 win at hapless Italians Zebre.
Toulouse's failure to get a bonus point, though, means they finish on 23 points, one more than Leinster but now reliant on other results to go their way to finish as one of the top four qualifiers.
"The objective was first of all to win but also to take the bonus point in difficult conditions," said veteran Toulouse wing Vincent Clerc.
"We did the minimum, we depend on others now but we hope it will go our way and we'll be hosting."
A bonus point would have meant that Munster could not surpass them and would have ensured that home tie in the last eight.
No such problems for Ulster who ended the group stages as the only team with a 100 percent record as South African scrum-half Ruan Pienaar exploited an error from Leicester fly-half Toby Flood to snatch victory for the Irish province.
The Tigers had led 19-9 after Flood's brilliant grubber set up a try for Niall Morris.
But Pienaar, who scored all Ulster's points, charged down a Flood clearance from inside his 22 and sprinted on to touch down before adding the conversion and a winning penalty.
It means Ulster topped Pool 5 with 26 points, making them the top seeds in the quarters, while Leicester will have to settle for qualifying as one of two best runners-up.
Toulon's victory, thanks to five Jonny Wilkinson penalties, ensured the reigning champions will play at home in the quarters.
They top Pool 4 with 24 points and will definitely be among the top three seeds.
"The aim was for a home quarter-final. We did that so it's mission accomplished," said Toulon centre Mathieu Bastareaud.
Flanker Chris Fusaro scored the only try of the game for Glasgow while Ruaridh Jackson kicked a penalty but the Scots ultimately came up short.
Cardiff Blues took second in the group despite losing 19-13 at home to Exeter Chiefs.
