Manchester United manager José Mourinho has three selection dilemmas ahead of Saturday's clash with Liverpool, according to Gary Neville.
Mourinho must make decisions on who to play at left-back and in the wide midfield positions at Anfield, with the other seven outfield players already decided, according to former United captain Neville, as per Sky Sports.
"Midfield, I think it will be [Nemanja] Matic and [Ander] Herrera," Neville said. "These six - [Phil] Jones, [Eric] Bailly, [Romelu] Lukaku, [Henrik] Mkhitaryan, [Juan] Mata and [Antonio] Valencia - will play.
"The question is whether he thinks [Ashley] Young can handle Salah and whether he brings [Matteo] Darmian in. He might come in as he defends with his right foot and Salah making those runs. Coutinho plays in that gap and space and with [Alberto] Moreno going forward, is Mata the person who can get back in there and then get up the pitch?
"Who plays left back - I think it will be Darmian. On that right-hand side, I think it will be Mata. And then, is it Rashford or Martial?"
In contrast, Liverpool's starting XI is easier to pick, according to Jamie Carragher, especially following the hamstring injury that has sidelined forward Sadio Mane for six weeks.
"Mane last season when being out, the record was not great. That is one of the reasons they bought Salah, as there was never anyone who could fill that role when he was not there."
"Now they found a way of getting the two of them in the team with Mane on the left-hand side and Salah on the right. OK you still have that pace and penetration, maybe not quite at the same level as Mane, but he has made a brilliant start to his Premier League career."
"This man Coutinho has been playing more of a midfield three, so I think he just joins the front three and you go back to how Liverpool set up last season in terms of that front three."
"OK, Salah for Mane and you would say [Adam] Lallana is missing from that midfield three. And if you think of last season against Man United, he went with that three - Georginio Wijnaldum, Jordan Henderson and Emre Can."
"And I think one of the reasons why I think he will do that is because you have two of your three midfield players in Can and Henderson who are 6ft plus."
