Jonny Sexton insists all is to play for in Pool Four after Racing Metro shared a draw with the Scarlets.
It appears a three-horse race in the pool with the West Wales region top thanks to points difference over the Parisians and Clermont Auvergne just a point behind.
Racing face Harlequins who have yet to register a win in Europe this term in the December double headers - kicking off at Stade de la Beaujoire.
"It's all to play for with one home win and a draw on the road," said Sexton.
"All the teams can beat each other. which is the good thing about this pool. We have back-to-back games against Harlequins and have to see how that goes.
"Clermont also have to come here to Parc y Scarlets. It's a really tough place to go, the Scarlets play some serious stuff and have some outstanding players."
Racing could have nicked a win at the death at Parc y Scarlets with the Ireland fly-half ripping the ball out of contact and Wenceslas Lauret eventually crossing - but the effort was ruled out by the TMO.
Sexton was disappointed with the decision and the result but reckons it was a fair reflection of a fiercely contested Heineken Cup encounter.
"It's bitterely disappointing not to get the win," added the Ireland fly-half.
"We were down to 13 men and losing by 13 points so we did well to claw our way back and never give up.
"We had a couple of chances to win it - I had a chance near the end to put us in front and then I thought we scored a try.
"It was an evenly contested game and a draw was probably a fair reflection even though we had a couple of chances at the end."
