I get the sneaky suspicion that there is a difference in English between areas, here.
Some are adamant about "Liverpool win" & some about "Liverpool wins".
I think some treat "Liverpool" as a team of players (plural) & others as singular.
Notice that according to the descriptions, you cannot easily avoid the issue:
"The Liverpool team" is still plural or singular, depending on the view.
Personally, I put "Liverpool" as a singular, "The Liverpool team" as singular & "the Liverpool team members" as plural, but I am far from Liverpool & maybe not a reliable reference.
