Gary Neville believes Jurgen Klopp should ignore the Champions League and focus solely on winning the Premier League with Liverpool this season.
The Reds have started the season superbly, recording four consecutive wins to take them to the top of the table, with just the one goal conceded.
A hectic seven-game run of fixtures between September 15 and October 7 however sees them play two Champions League matches against Paris Saint-Germain and Napoli before a visit from Red Star Belgrade at Anfield on October 24.
Klopp re-established the Reds as a force in European football last term as they went all the way to the final before a 3-1 defeat to Real Madrid in Kiev on May 26.

Reds supporters were able to savour a number of memorable nights as Klopp's swashbuckling side beat Porto, Manchester City and Roma en route to their first final appearance for 11 years.
However, Manchester United legend Neville believes the Reds should forgo a genuine attempt to win their sixth European Cup in favour of a first league title in 29 years.
In an interview with The Times, Neville said: "The Champions League - if I was Liverpool, I would kick it into touch.
"I know that’s very hard to do but if they could go into February, March, April without it, I think they could have a real chance if they had free weeks.

"Why? I think their method is exhausting for the front three [Mohamed Salah, Sadio Mane and Roberto Firmino]. The drop in quality below them, if there are injuries or playing Wednesday, Saturday, I think it will take its toll."
Neville has carved out a reputation as one of the most well-respected pundits around since taking up a job with Sky Sports in 2011, but he admits that as a United supporter, Liverpool's form is difficult to watch.
"But, as a United fan, I am very concerned about them," he added. "This front three have always been fantastic and now the midfield can run, it can pass, it has depth. And the back four looks a unit.

"The football they are playing under Jurgen Klopp, it’s fantastic. As a United fan, that’s a worry because it is still that mentality of ‘anyone but them’.
"Same for them, anyone but us. That’s not ‘Gary Neville he’s a Red, he hates Scousers’. Those days have gone. I am more thoughtful now.
