When Liverpool and Man United clash at Anfield on Sunday, there will be more at stake than just the usual bragging rights.
We take a closer look at three contests that will define the vital showdown:
Bailly has struggled for form and fitness throughout his United career, but the Ivory Coast centre-back has been key to their winning streak.
In six games with Bailly in the team, United have won five and drawn once, conceding just three goals.
Harry Maguire looks more comfortable alongside Bailly, whose out-going personality kept his team-mates relaxed during their difficult periods earlier this season.
Salah, Sadio Mane and Roberto Firmino are a formidable test for United’s rearguard, although they have gone through a barren patch of late, with Liverpool netting only once in their last three league games.
JORDAN HENDERSON V BRUNO FERNANDES
Widely credited with reviving United with his fierce will to win and positive attitude, as well as his classy performances, the Portugal playmaker’s next mission is to stamp his authority on the biggest game of his time with Ole Gunnar Solskjaer’s side.
Fernandes, signed from Sporting Lisbon last January, will head to Anfield as the first star to win the Premier League Player of the Month award four times in a calendar year after earning the prize for December.
Overall, he has 15 goals and nine assists in all competitions this term, making it 27 goals and 17 assists in 48 United appearances.
Ravaged by injuries to his top centre-backs, Klopp will be forced to deploy Brazil midfielder Fabinho as a makeshift defender once again.
Virgil van Dijk and Joe Gomez are long-term absentees, while Joel Matip has spent the last week battling to return from an adductor injury for the last three games.
Matip has returned to training but if he is not deemed ready then Klopp will have to choose between youngsters Rhys Williams and Nat Phillips to partner Fabinho.
“It’s a test and reality check of where we’re really at because we’ve won many, many tight games, scored a few goals in injury time, showed that mentality.”
