Saracens director of rugby Mark McCall admitted his side under-performed in their 29-20 victory over Northampton in the Champions Cup on Saturday.
Trailing for a large part of the match, hosts Saracens finally clicked into gear in the second-half as they booked a place in the semi-final.
Chris Ashton and Chris Wyles were their try-scorers while Owen Farrell kicked 19 points, leaving McCall content with securing the result.
"It was a complex game for us and we didn't play anywhere near as well as we can," he told EPC Rugby following the win at Allianz Park.
"But we have been in worse positions that than before on the scoreboard and we just needed to turn the game in our favour.
"We put ourselves under pressure but good teams find a way to win games and I am pleased with our second half display.
"This is the first game of the season where everything has been on the line so to come through it like that it pleasing."
Meanwhile, Northampton captain Ben Foden believes his team left plenty of points on the field after the first-half.
"We are obviously very disappointed but we know we've come up against a very good Saracens side," he said.
"I asked for a big performance from the boys and they gave it to me. We are a bit like the walking wounded at the moment with so many injuries and we picked up a few more but they gave everything they had out there.
"We probably had the bounce of the ball in the first half but know that we left a few points out there that could have made a real difference.
"But that's sport. Once they got back into the game and we picked up a few injuries our heads dropped a bit and that's when the game started to get away from us."
