It’s Sergio Conceicao’s Porto again for Jurgen Klopp as the Reds meet them in the Champions League for the fifth time in just over three and a half years.
Klopp can take comfort in the fact that his two visits to Estadio Do Dragao as Liverpool boss saw a total return of 9-1.
Much for Liverpool’s analysis team to think about as they chart their way to six points in Group B.

But what are the burning issues the Reds boss needs to tackle before he takes to the skies?

Midfield injuries bit at an inopportune time for Klopp.
With Harvey Elliott and Thiago Alcantara sidelined, the Reds lacked an element of control in the middle of the park on Saturday as they succumbed to the frenetic game Brentford desperately wanted to draw them into.
Naby Keita, however, is someone who could potentially calm things down in the engine room.
But, as is usually the case with the Guinean international, questions about his physical form persist.
“Nothing really serious but keeps him out of the next game for sure,” was Keita’s diagnosis on Friday by Klopp after his withdrawal from Norwich on Tuesday after kicking the ground.
” May be [he’ll be out] a little bit longer. You have to see there too.

“It’s nothing serious but it’s obviously painful and we have to see how we’re going to handle this. “
Expect an update on Keita’s condition when Klopp speaks to the press on Tuesday.
With Manchester City coming to Anfield on Sunday, Klopp could use all his resources this week and a Keita return would be of great help.
It was a collective night’s rest for the Liverpool defense at Brentford Community Stadium.
The Reds have scored as many goals in 90 minutes as in the previous seven games.
It would be hard to be too critical of what had been the best backline in the league so far, but Klopp is hopeful that normal service will resume in Portugal.
Given their performances so far, it’s easy to forget how little Virgil van Dijk and Joel Matip have played in football in 2021 and that could partly explain the decline in form in West London.
Both players will redouble their efforts to exclude the Portuguese on Tuesday, if they are selected, but Klopp could also create a surprise at the back.
After all, he used the 3-2 win over AC Milan earlier this month to rest and rotate as Joe Gomez was called up in place of Van Dijk.

The last 25 minutes or so of the weekend saw Liverpool play in an adventurous 4-2-3-1 system.
It featured their four main forwards with Diogo Jota and Sadio Mane on the right and left wing, respectively, with Roberto Firmino hidden behind Mohamed Salah.
The switch, which saw Firmino replacing Curtis Jones for his first appearance in a month, was initially put in place before the midfielder was ruled out in Liverpool’s third, but Klopp decided to stick with the substitution nonetheless. .
“I actually think it worked really well,” Klopp said of the offensive movement.
“We didn’t score from the situations, but Bobby (Firmino) had some very, very good situations passing, giving the ball away.
“We had huge chances and even in the last second (there was) a big one.
“That was the reason. We thought we could score more goals to get a result.
It’s a formation that has been used sparingly by Klopp since Jota signed with Wolves a year ago and what she lacks in midfield control she makes up for by attacking the threat.
Could he unleash himself on Porto from the start?
