Pool 1 Review
Three time champions Leinster are back in the driving seat as they try to make up for missing out on the quarter-finals for only the second time in the past nine seasons in 2012/13. Their 19-7 home win over French champions Castres Olympique put them three points clear at the top of the table.
Now they face back-to-back clashes with the side they beat at the Millennium Stadium in the 2011 Heineken Cup final, Northampton Saints. The Saints inflicted a second successive defeat on the Ospreys and their 27-16 triumph included three tries to more than make up for their first round defeat in Castres.
The two teams have met three times in the tournament and Saints are still looking to break their duck. The fact they will start with home advantage in round three on Saturday, 7 December will at least give them some help.
Castres are still not out of it in third place with four points, but they will need a good return from their two games with the Ospreys if they are to threaten the top two. They will also start at home, on Friday, 6 December.
Pool 2 Review
Everybody has won a game in this Pool following Cardiff Blues amazing upset of reigning champions Toulon at the Arms Park and Glasgow Warriors home triumph over Exeter Chiefs. The Chiefs sit on top of the Pool on try count in what is only their second season in the tournament.
The top two teams will now met in the back-to-back matches in December, with Rob Baxter's Chiefs facing arguably the biggest game in their history on Saturday, 7 December at Sandy Park when they host Toulon.
The Chiefs led 9-6 at Glasgow in round two, but couldn't hold on and eventually went down 20-16. That earned them a bonus point, though, with Dave Ewers try in the 75th minute proving crucial.
At the Arms Park the Blues went through 80 minutes against the European champions without conceding a try - some feat when you remember they leaked six against the Chiefs in round one. Jonny Wilkinson kicked five penalties to give his side a 15-12 lead going into the final 10 minutes, but try at the posts from replacement outside half Gareth Davies three minutes from time changed the whole course if events.
Leigh Halfpenny slotted the conversion and the Blues were in dreamland with a 19-15 victory over the side that had done the double over them on their way to the title last season. The Blues now face fellow PRO12 side Glasgow Warriors in December, starting with a vital home game on Friday, 6 December.
Pool 3 Review
Saracens and Toulouse rasied up the UK and Ireland Heineken Cup Pool attendance record to 61,248 at Wembley Stadium, but it was the four-time champions from France who left with the points. A try from French No 8 Louis Picamoles in the second half sealed a 17-16 away win that put Guy Noves' men four points clear at the top of the Pool.
Saracens picked up a bonus point in defeat, with USA centre Chris Wyles getting his second try in as many games, but they will need to pile on the points in the home and away games against Zebre in December if they are to make up ground on the leaders.
Zebre were beaten 33-6 at home by Connacht as all four Irish provinces enjoyed victories. Pat Lam's side now face back-to-back games with Toulouse, starting away in France on Sunday, 8 December. They can still have a massive impact on the Pool if they can pick up points in those two games.
Pool 4 Review
The Scarlets and Racing Metro 92 lead the way after sharing a draw in west Wales, but last season's Heineken Cup runners-up ASM Clermont Auvergne are breathing down their necks after extending their unbeaten home run to 65 games against Harlequins.
The 26-26 all stalemate at Parc y Scarlets ensured the Welsh region clung onto pole position on six points thanks to tries scored. Racing Metro, who almost snatched a last gasp victory, are just two tries adrift of the early pacesetters.
A relieved Scarlets coach, Simon Esterby, now has to face a double dose of Top 14 opposition in December with back-to-back games against Clermont. The two sides have four times before in the Heineken Cup and the Scarlets have yet to win.
Clermont scored three tries and 20 points in the opening 25 minutes of their game with Harlequins, but only won 23-16 in the end without a bonus point. It was a second defeat in a row for the Quins, who travel to France once again in round three to take on Racing.
Pool 5 Review
Ulster Rugby are in pole position to advance to a potential fourth successive Heineken Cup quarter-final after maintaining their winning start with an impressive 25-8 victory at Montpellier - the French club's first home loss this season.
The 1999 champions had kicked-off their campaign with a hard-fought win over Leicester Tigers and they have now stretched their winning run this season to five matches and sit two points clear of the English champions.
Mark Anscombe's men face Benetton Treviso in back-to-back matches beginning at Ravenhill on Saturday, 7 December. They have faced the Italians four times previously in the Heineken Cup, winning every encounter, and will be targeting maximum points to put one foot in the knock-out stages once again.
Leicester maintained the pressure on Ulster with a bonus-point victory over Benetton Treviso. They welcome Montpellier to Welford Road on Sunday, 8 December. The two-time champions have never faced Montpellier in the Heineken Cup before, but will be under no illusions of the important to record a win to keep the pressure on Ulster.
Pool 6 Review
James Hook has steered Perpignan to the top of the Pool with 33 of his side's 53 points in the opening round defeat in Gloucester and the bonus point win at Stade Aime Giral over Edinburgh. That win, along with Munster's Thomond Park triumph over Gloucester mans that everyone has won a match in the Pool.
Perpignan's two bonus point have carried them to the top of the table and they hold a one point lead over Munster going into the back-to-back rounds in December. They travel to Thomond Park on Sunday, 8 December for what will be the eighth meeting in the tournament between the two teams.
Only two points separate Perpignan at the top and Gloucester at the bottom of the Pool, which there is all to play for in December and beyond. Gloucester will head to Edinburgh in round three when they will seek to return to winning ways after going down 26-10 in Limerick against Munster.
