So, what we do we know ahead of kick-off?
Roberto Firmino travelled with the 23-man Liverpool squad that set off for Barcelona yesterday, having missed the win over Huddersfield Town due to a slight muscle tear. Klopp intends to make a decision on the No.9’s availability later today.
Fabinho also made the journey and is fully fit, while Alex Oxlade-Chamberlain and Rhian Brewster are with the team in Spain, too.
Lionel Messi, who clinched the La Liga title for Barcelona on Saturday with a goal as a substitute, is ready to face Liverpool after being rested recently.
“Messi has been rested but we’ve had three league games within seven days, we’ve had the games with Manchester United and it’s been a very heavy workload,” said coach Ernesto Valverde.
