Director of rugby Mark McCall was frustrated after Saracens made hard work of beating Biarritz 20-16 - and missed their chance to secure a Heineken Cup quarter-final place one week early.
Biarritz's losing bonus point means the group will not be decided until next week - but Saracens can book their passage into the last eight with a single point in Treviso.
"We are pleased to have won the game," McCall said. "These kind of games are about getting the job done. There is a little frustartion it wasn't more simple than it turned out."
He added: "There were times in the first half and the start of the second where we were very dominant and at 14-6 we had an opportunity to pull away and break them.
"We couldn't do that but the last 20 minutes characterised everything we are about as a club with the the work ethic and discipline.
"We are not quite qualified yet. That will definitely focus the mind for next week. It is very important we are professional."
McCall was full of praise for his pack and three young England stars.
Owen Farrell has attracted all the headlines of late but full-back Alex Goode enjoyed another outstanding game and Ben Spencer caught the eye at scrum-half.
"The reason Ben didn't make the Saxons is because the RFU like them to go through their age groups," McCall said.
"Ben has never represented England at anything and this is an opportunity to play for the Under 20s in the Six Nations."
