Champions Cup round-up: Drew Mitchell saves Toulon as Wasps beaten, Racing Metro run in nine tries in rout of the Scarlets

Now Dai Young’s side must beat Leinster at home next weekend to go through.

When the two sides met in November, Toulon were unrecognisable and Wasps cruised to a handsome 32-6 thrashing.

It was very different this time around, though, as the European champions dominated the early exchanges.

A desperate last gasp double-tackle from Sailosi Tagicakibau and Joe Simpson prevented Bryan Habana from scoring a certain try in the left corner.

But it was Habana himself who helped create the game’s opening try on 12 minutes.

The South Africa wing intercepted the ball inside Toulon’s 22 and started a counter-attack that saw Josua Tuisova break down the right wing before passing inside to Quade Cooper to score.

Habana was in the thick of things and it was he who was barged into touch by George Smith after he’d kicked ahead that saw Wasps find themselves down to 14 men as the Australian international flanker was sent to the sin bin.

Eric Escande kicked the resulting penalty but Wasps managed their numerical disadvantage expertly, pushing Toulon back inside their own half before earning a kick of their own in front of the posts, which New Zealander Jimmy Gopperth didn’t miss.

Toulon replacement fly-haf Frederic Michalak missed a simple-looking kick before the hour mark, after which Gopperth reduced the arrears with his own successful attempt.

Ten minutes from time, Elliot Daly brushed off Nonu in midfield and helped set up Guy Thompson to crash over in the corner, breaking through one tackle, handing off a second tackler and resisting the attentions of two further Toulon players to score.

Wasps looked set for a famous win but Toulon demonstrated why they have ruled Europe for the last three years as Mitchell had the last word.

Racing ran in nine tries in their rout of the Scarlets with All Blacks star Dan Carter amassing 13 points with the boot.

That means they cannot be caught at the top of Pool 3 by Northampton, who needed a last gasp try from coach Jim Mallinder’s teenage son Harry to secure a 19-15 win over Glasgow.

Samoan-born former New Zealand international centre Casey Laulala scored a hat-trick but the try of the game was a brilliant individual effort from young Frenchman Louis Dupichot.

The match was over as a contest long before half time as Racing ran in five converted tries for a 38-0 advantage.

The big-spending French outfit even had the luxury of taking Carter, who had started the game at inside centre with Remi Tales at fly-half, off after 52 minutes.

Scarlets’ fifth loss in five games was the Celtic League leaders’ record defeat in the competition, surpassing a 41-0 hiding suffered at Clermont in 2008.

Northampton outscored Glasgow by three tries to nil but still needed a 78th minute try from 19-year-old wing Mallinder after four penalties from Finn Russell and one from Stuart Hogg had given the Scots an unlikely lead at Franklin’s Gardens.
