But they are unlikely to have done so in such a setting as exotic as Miami, the host city for the final of the International Champions Cup.
Florida may be a world away from Merseyside and Manchester yet expect a healthy following for both teams who have strong fanbases in the United States.
Paddy Power make Liverpool the outsiders at 2/1 (3.00) while United are offered at 5/4 (2.20) and the draw can be backed at 23/10 (3.30).
It is understandable that Louis van Gaal's side are fancied by the bookmakers, given what we have seen from them so far in the USA particularly last time out in their 3-1 victory over European champions Real Madrid.
The Red Devils looked sharper than the Liga outfit and they will be hoping to continue that form in the early hours of Tuesday morning.
Overall this has been a pretty high-scoring tournament, and over 2.5 goals in the match is offered at 4/6 (1.65).
However for some more value the price of 10/11 (1.91) for United to score two or more goals is extremely inviting.
Having netted three against Madrid as well as three against Roma, the side from Old Trafford have shown they have goals in them.
Liverpool meanwhile conceded twice against Manchester City in their only other encounter with a Premier League team in the tournament and, with United full of confidence, there's every chance they can find the back of the net twice.
