Liverpool beat Genk 4-1 away on Wednesday night to get their second win in the competition this year.
Alex Oxlade-Chamberlain’s wonder strike set the holders en route to an impressive win in Belgium.
Just 24 hours earlier, Tottenham had got their Champions League campaign back on track with a 5-0 win over Red Star.
Harry Kane and Son Heung-min both scored doubles while Erik Lamela completed the rout at the New Tottenham Stadium.
This Sunday, the two Premier League giants will meet at Anfield, with Jurgen Klopp’s side looking to extend their lead at the top of the table.
Spurs were on the back of a three-game stretch of poor results – having lost 7-2 to Bayern Munich, 3-0 to Brighton, and drawn 1-1 with Watford – before the game against Red Star.
However, Klopp insists his side will provide a different challenge to Red Star.
“It’s all good, I didn’t enjoy the game too much but I enjoy the result a lot,” he said after the win over Genk.
“I don’t know, that’s not too important,” he replied when asked if his team is at top level. “I don’t think we have to do too much.
“We had two away games now, with United and this one, they were both difficult for different reasons.
“I don’t know where we are now, that’s not too important, I know where we have to be on Sunday, that’s for sure.
“That’s a different story anyway.
“Absolutely [a big game], against a refreshed Tottenham. The second before they meet us they are back on track.
“Obviously they played a good game yesterday, but we are a different team to Red Star Belgrade, and Tottenham is different to Genk, that’s how it is.
“Luckily we have an extra day to prepare for Sunday than we had for this game, that will help because you have Sunday-Wednesday is semi-cool, but we played and got four points, that’s better than nothing.
“Now, let’s prepare for Tottenham.”
