Jamie George admits Saracens losing control of their own European Champions Cup destiny is disappointing following a 15-15 draw with Ospreys.

Sarries face Northampton in their final Pool Two game next weekend knowing they require a five-point maximum to have any hope of reaching the quarter-finals as one of three best runners-up.

The result also saw England number eight Billy Vunipola suffer a fractured arm, with Saracens also losing Vunipola's back-row colleagues Michael Rhodes and Jackson Wray to injuries on a disruptive night at the Liberty Stadium.

The Champions Cup holders' hopes of progressing in Europe have been drastically reduced as they seek a hat-trick of titles and hooker George is keen to avoid a first pool-stage exit since 2011.

"We are gutted because we are now relying on other people," he said. "We are now not in control of it.

"Obviously, we are in control of our performance, but we are hoping for stuff elsewhere, which is the most frustrating thing.

"Northampton got a good result (against Clermont Auvergne), and they are going to be looking to get one over on us, having had two bad results against us already this season.

"It (Europe) is everything. The best memories I have had in a Saracens shirt are winning those two finals.

"As an aspiring club, we want to test ourselves against the best. We are hopeful that results go our way over the next week, and we are able to carry on in this competition.

"The way we performed against Clermont at home (Saracens lost 46-14 last month), that was nowhere near good enough. That was the worst performance I have been involved in in a Saracens shirt. It was very, very disappointing.

"But we have bounced back pretty well. The way we performed away at Clermont was actually one of my favourite games I've played. We didn't get the result, but we played well and potentially should have got the result."

Saracens beat Northampton 57-13 last time the sides met, but George is wary of attempting too much too soon at Allianz Park.

"It's trying to find that balance between knowing that you need to get the five points, but at the same time, you don't go chasing the game," George added.

"If you go chasing the game, you get loose, and that's not how we play the game. We play the game with a good structure."

George believes his England colleague Vunipola "looked back to his best" before suffering another injury blow.

Vunipola lasted just 40 minutes of his second game back in action after three months out with knee trouble.

"The way that he performed in the first half, and last week (against Wasps) in particular, he looked back to his best," George added.
