Toulouse fly-half Toby Flood has admitted that the players' minds were elsewhere in their meeting with Saracens last Saturday.
Flood carefully added that the side weren't using the effects of Friday's shocking attacks in Paris as an excuse, but couldn't ignore how the news had distracted the squad.
Saracens were 32-7 winners in the Round 1 fixture held at Allianz Park.
Flood added that Saracens had played the conditions perfectly, even if their style wasn't easy on the eye.
"We did not want to use Friday's events as an excuse. But running out onto the pitch, you could see that the guys were not fully in their zone," Flood told the EPC Rugby website.
"That said, Saracens were the better side. They know exactly how to play like Saracens. It's not necessarily beautiful, but it is very effective.
"In the first half, the wind was at their back, they played exactly as you should do in those conditions
"It's brought us back down to earth. We must understand what happened because it is complicated. It was a big test against a team that can win the European Cup. And we lost.
"It hurt us to lose this game but it was very tough 48 hours for all players who have friends or family who live in Paris. It also makes you sadly realise that there are much more important things than rugby."
