Liverpool boss Jurgen Klopp says he watched “pure quality” in the Champions League this week - but insists he didn’t see anything to scare him.

The Reds are on the brink of securing their passage to the quarter-finals after an emphatic 5-0 first leg win over FC Porto and Klopp has been studying the other last 16 battles with interest.

Bayern Munich’s demolition of Besiktas and Chelsea’s draw with Barcelona was followed on Wednesday by Shakhtar Donetsk beating Roma 2-1, while Sevilla and Manchester United fought out a goalless draw.

“I watched all the games,” Klopp said.“I saw pure quality. I knew that Sevilla were still really strong so I wasn’t surprised. It was a completely normal game that United played there.

“All the others – Shakhtar Donetsk was maybe a surprise for a few people but they have quality. They are still in their winter break and that makes it very special for them what they achieved against Roma.

“I know all the teams but it is nice when you are involved and you need to watch it. We play United in two weeks so I needed to watch that and we could play Sevilla again if we go through.

“I was not worried before I watched all the games, I am not worried now. All I know is that they all have big quality.”
