Saracens boss Mark McCall was delighted with his side's grit and determination after they came from behind to defeat Racing-Metro.
The visitors scored a 37-28 win despite a dismal period which saw David Strettle stretchered off, Will Fraser sin-binned and Racing lead 22-9.
Ultimately though, a record 10 penalties from Owen Farrell in a 32-point haul lifted Saracens to the brink of the quarter-finals to delight McCall.
"It was a fantastic performance," he said.
"In the last four years we have been building in this competition and a win against a very good French side in France continues that.
"We're very proud of the team after bouncing back from the setbacks in the first half of the early injury, the tries and a yellow card.
"We were off our game in that first half and not working hard enough. But we knew at half-time that if we rectify things then we could win the match.
"But we still have an important job to do next week against Edinburgh to secure the pool winners spot."
