In terms of h2h, Manchester United facing Tottenham is actually not too good where in the last 5 matches even Mancheester United can only win 1 draw and 4 defeats so what makes Manchester United a better club than Tottenham at the moment?

I don't feel that Mancechster United are superior to the current conditions even though their chance to win is clearly very much there because indeed maybe the consideration is to the big name and previous experience but that does not guarantee now because everything can still happen including in the race for the trophy this time.
Man, sorry but h2h doesn't matter in european competition. I remind you when Chelsea often lost to the Arsenal in the league, but they won UEL by beating Arsenal 4-1. I'm stick in the same scenario that happened to the Manchester United.
Their performance is crap in the league, and can be considered as the worst. However, they have equal chance to win UEL or a bit higher.
We know so well the history of MU in european competition. I'd not judge them based on their h2h against Tottenham. Better to stick on the reality to happen soon.
I still have my trust for MU, though people underrated them at this moment. They have enough prep to face Tottenham.
Betting on them still giving us sense odds.
