PARIS (Reuters) - RC Toulon continued their run towards a third consecutive European title after they survived a late challenge to beat Wasps 32-18 and reach the last four of the Champions Cup on Sunday.
Saracens earlier sealed a dramatic 12-11 win at Racing Metro to reach the other semi-final in St Etienne against Clermont Auvergne.
Toulon flyhalf Frederic Michalak had a 100 percent kicking rate with six penalties and two conversions while the French side scored two tries through Mathieu Bastareaud and Ali Williams to set up a semi-final meeting in Marseille with Ireland's Leinster, 18-15 victors over Bath on Saturday.
England's Wasps, who failed to make their possession count, also managed two tries through William Helu with Alex Lozowski and Andy Goode kicking the rest of the points.
"We've got the squad to go all the way," man of the match Michalak told BeIN Sport.
At their Stade Mayol, Toulon made a perfect start when Bastareaud ran onto a Michalak pass to score between the posts.
Michalak added the extras and slotted home five penalties in the first half to put the hosts 22-6 up at halftime after Lozowski had kept his side just afloat with two penalties.
Toulon, who squandered a 18-0 lead before losing to Toulouse in the French Top 14 last weekend, got a tad shaky when Helu touched down after benefiting from some poor defending by Josua Tuisova.
Bernard Laporte's side let their guard down again, letting Helu dive over after the ball was played wide. The stage was set for a nervy finale but Williams put the result beyond doubt with a late try.
Earlier, Argentine centre Marcelo Bosch kicked a last-gasp penalty to send English outfit Saracens into the last four.
Bosch kept his composure to slot over a 43-metre kick after the clock had ticked past 80 minutes. Racing were trying to see out time while in possession but Fabrice Metz was penalised for going off his feet in a ruck.
Sarries will travel to France again for a last four meeting with Clermont after the Top 14 side dismantled Northampton 37-5 on Saturday.
"I told him (Metz) many times to keep his feet on the ground," Racing scrumhalf Maxime Machenaud, who scored all his team's points with a try and two penalties, told BeIN Sport.
Charlie Hodgson kicked an early penalty as Racing were sanctioned in the scrum.
Saracens were reduced to 14 men when Jim Hamilton received a yellow card for collapsing a maul near his try-line and Racing quickly benefited with Machenaud diving over after the pack had come close following a lineout.
Hodgson then missed two penalties in quick succession before finding his range again early in the second half to put his side ahead.
Racing were penalised for going off their feet at the ruck and fullback Alex Goode stretched the visitors' lead to four points.
Machenaud put his side ahead with a couple of penalties but another lack of discipline cost them dearly.
