He said: "I believe we have been heading in the right direction and that our league position is not an accurate reflection of our potential.
"We go into every game expecting to win and this is no exception. We want to bring Saracens back to Hughenden with us in front."
Sean Lineen also thinks Glasgow have to take something from Sunday's game. He said: We have a few points to prove. We're bottom of the Celtic League and Europe is all we have left - we have to go there and get a result. The players are good enough, now it's time for them to put their hands up."
Saracens have named a strong side for Sunday's match including Kyran Bracken, Thomas Castaignede and Taine Randell.
Saracens: R Haughton, D Cech, P Bailey, B Johnston, D O'Mahony, T Castaignede, K Bracken, S Sparks, R Ibanez, C Visagie, S Raiwalui, A Codling, B Skirving, B Russell, T Randell (captain)
Replacements: R Russell, E Bergamaschi, B Broster, K Chesney, M Williams, N Little, R Peacey
