The arch-rivals’ fortunes have been in stark contrast this season. With only nine points from eight matches, United have got off to their worst start in 30 years.
They are 15 points behind Juergen Klopp’s European champions, who have extended their perfect start to eight matches.
But Solskjaer insists that the blockbuster fixture will bring the best out of his men.
“That’s a perfect game for us,” Solskjaer said, after their 1-0 loss to Newcastle United on Sunday, following a winner by 18-year-old debutant Matthew Longstaff.
“The international break is also at the perfect time because their heads need a bit of airing.”
