"We weren't anywhere near our best today. We couldn't get any momentum into our play and we ended up getting sucked into a game we didn't want to play," admitted McCall.
"Toulouse played field position and they defended. They counter attacked from time to time, they made life very tough for us and we simply ran into a team right at the top of their game.
"That wasn't the best of the Saracens and, hopefully, we can give a better account of ourselves in the future. They are still a pretty good team in Europe, but there were areas of our game where we were nowhere near our best.
"Your set piece has to be good to gain momentum and although our scrum was good our line out didn't function. They seemed to get their first-half points pretty cheaply, they had a couple of excursions into our half and seemed to come away with points.
"We seemed to have to work unbelievable hard for our points - it was a bit of a slow death out there. But it has happened and we have six days to turn things around for Connacht, which is a huge game.
"If we can win that game we get the chance to go somewhere else in the quarter-finals and prove we are better than we were today.
"We have a physically battered changing room and we have to play Connacht in six days time. There is something at stake for them - whoever wins that game could qualify and so it is a huge game."
