The goalless draw takes the Light Blues through to the third qualifying round where they will play Midtjylland of Denmark.
Speaking to RangersTV in Luxembourg, Gerrard said: “I thought it was a grind the whole night. Our performance was a grind to watch and I’m sure it was a grind to play in.
“I thought we were better in the second half and we looked more dangerous and more creative, certainly in the final 20 minutes. We maybe should have won the game and I thought we created enough to win the game, but still, I don’t think it would have changed my mind on the whole performance.
“Look, we have done enough and we have gone into the next round, it is a clean sheet and we will take that and move on.
“But I didn’t enjoy watching it – it was just a bit of a grind. We should have got through last week and I think when you’re not creative and you’re not ruthless in front of goal, we left ourselves work to do tonight and in the final third, there wasn’t enough imagination, enough people risking the ball until the final 20 minutes, then we just couldn’t finish our good play off.
Gers move onto face Kilmarnock in Sunday’s SPFL Premiership opener, and the manager continued on that: “We are all fine and we have no injuries or no knocks. We are hoping Steven Davis is going to be fit and available for the weekend and we have rested a few tonight with an idea for the weekend, so we are in good shape.
“I think it is important just to move on from this game and take the positives from qualification.
“But we are going to have to play better if we want to get to the group stages.”
And, while the tie against the Danes next week is sure to be a step-up, the manager added: “I think that might help us. When you come to places like this, they’ve had the heating on in the dressing room, the ball is like a balloon and the pitch is bobbly and dry, they just foul at every given moment and the referee gives every foul – it’s just one of those nights.
“I won’t even watch this game back.”
