Liverpool boss Jurgen Klopp says the 1-1 draw at home against Rubin Kazan is a step forward for his side.
It was the German's first match in charge of the Reds at Anfield since he took over from Brendan Rodgers.
With Sion winning away from home, Liverpool keep their second position in Group B ahead of November's away match against the Russians.
"Everybody could see they are not too bad – very experienced, very cool when they got the ball," Klopp said.
"They didn't have it too often but when they had the ball they were really good.
"They got the first goal and that's one of the biggest challenges in football. You are in a good moment, your direction is OK, you're in the game, your concentration is high and you're playing football and you have this. You need to restart in the game but we did it well and made our goal.
"Before that they got the red card. Sometimes it's a big advantage against 10; most of the time it's a really thankless job because now they stop playing football. Now they defend in a big, compact block.
"That's what we had to do better tonight, but we had our moments, we hit the post with Christian. We had some other moments – good chances – but at the end, no goal.
"So I would say 98 per cent OK, not perfect, but the last two per cent – the decisive per cent – we missed. That was the problem this evening.
"Sion won their game so they are away [at the top of the group], maybe away. We have a situation that we can come back but of course the next game in cold Kazan is the next challenge.
"Tonight wasn't a masterclass but it's not the worst day in my life. In the next game we have to work hard – that's what we did tonight – and we'll go on like that."
