It was the Andy Goode show at Sixways Stadium as the outside half scored all Worcester Warriors' points in a tight 22-21 win over Perpignan that edged them three points clear at the top of the group with everything now resting on the return tie at Stade Aime Giral in Round 4.
Goode - despite the close attentions of a trio of Perpignan defenders - managed to force his way over close to the posts for his side's only try in the 32nd minute.
His trusty boot did the rest with the conversion of his own try along with five penalty goals, the final two in the 65th and 77th minutes denying Perpignan a priceless away win.
And opposite number James Hook saw his final minute drop goal miss the target as the relieved Warriors' fans were left to celebrate their 11th win against French opposition in 20 tournament matches.
A feisty contest saw Welsh referee Neil Hennessy send four players packing to the sin bin - Neil Best and Ceri Jones from the home side and Perpignan's Sona Taumalolo and Adrien Plante - as Perpignan ended up outscoring the home side 2-1 in tries.
Scrum half Florian Cazenave got the first, after powerful work by lock Sebastien Taofifenua, with the second coming in the shape of a penalty try midway through the second half.
Welsh international Hook did land a conversion, drop goal and two penalty goals but it was Goode's show.
