I don't see Pep taking chances with regards to players fitness and form, and if anything he will go quite conservative with the lineup.
Khusanov and Rodri are in our best team, but right now they just don't have the fitness or form for a game of this caliber.
Bernardo is his reliable soldier on the field and is almost certain to play meaning it's probably going to be him, Foden and Nico G in midfield.
I wouldn't be at all surprised if Savinho and Doku are on the wings.
It's a must win game regardless for me. I know many are saying there are still 80 odd points to play for etc.. but if we lose that's 4 losses in the league after 11 games and 9 points behind top spot. You cannot be losing more than a third of your games at this stage of the season as history shows that anymore than 5 losses in a season and it's incredibly difficult to win the league.
I think the league has been won by 6 losses only 4 or 5 times and nobody has won the league with more, and in most cases those extra few losses for those teams have come after they won the league early. Lose here and we would have to be bordering on perfect for the rest of the season.
It's the same for Liverpool.
