It has been four years since a representative from the Aviva Premiership claimed European rugby's greatest prize, hamstrung by a restrictive salary cap and an attritional domestic league.
Irish sides have dominated the tournament in recent times with reigning champions Leinster and two-time winners Munster triumphant in three of the last four years.
Their scope to rest players so that they are at their peak for European competition gives them an enormous advantage, while well-resourced French clubs operate within a much higher salary cap.
Northampton defied the odds to reach this year's final where they were beaten 33-22 by Leinster in a gripping contest and later cited fatigue as the reason for their second-half collapse.
Booth, however, believes Saints' presence at the Millennium Stadium last month and the number of English qualifiers proves the Premiership remains a force to be reckoned with.
"Without question the Heineken Cup has got harder than ever to win," he said.
"The Premiership's getting harder year on year and in general rugby's improving.
"Look at the Irish sides and the way they monopolise the tournament.
"They have various playing resting aspects that makes them very tough to compete against.
"It's the competition we all aspire to be in so we have to roll up our sleeves and get on with it.
"The fact Northampton reached the final of the Heineken Cup proves that English teams are still capable of winning it.
"What also bodes well is that we have seven English teams in there, more than any other country.
"That highlights the fact the Premiership is still a very competitive league, but at some point an English team must break the mould and actually win it."
Booth was quietly encouraged by today's draw which placed Irish in the same pool as Cardiff Blues, who failed to reach the knockout stages this season, Edinburgh and big-spending Racing Metro.
"We're in the group of entertainment because there's a lot of positivity there in the way the game is played," said Booth.
"Edinburgh play expansively, Racing Metro have a Harlem Globetrotters all-star line-up and Cardiff Blues only know one way to play as well.
"From that point of view it should bode for some entertaining rugby if nothing else.
"Compared to last season I'm a little bit relieved by the fact we're not in the group of death, as it was described because we had Munster, Toulon and the Ospreys."
As ever, there is no shortage of pools packed full of the potentially epic contests that have become a hallmark of the Heineken Cup.
Northampton and Munster collide in a tricky looking Pool 1, while Leicester must battle past Clermont and Ulster in Pool 4.
Aviva Premiership champions Saracens have managed to avoid any previous Heineken Cup winners, but Biarritz and Ospreys will provide challenging opposition.
The draw has been kind to Leinster with the champions grouped alongside Bath, Glasgow and tournament debutants Montpellier.
Two English clubs occupy Pool 6 with Harlequins and Gloucester competing with Connacht and perennial title challengers Toulouse for a spot in the last eight.
"Every team in the Heineken Cup is going to be tough, but I'm pretty happy with the draw," said Quins full-back Mike Brown.
"We know Connacht pretty well, we seem to play them every year. Toulouse are a world class team with world class players.
"We played them a couple of years ago and did all right at home.
"We take a lot of confidence from beating Munster at Thomond Park and hopefully we can do something like that again."
