I didn’t watch the match between Man United and Atalanta but I feel like even if my bet was small I would’ve probably been shouting during the second half. Lol. I mean after feeling all comfy in the first half, thinking it’s already money in my pocket and all. 
I think atalanta's fault was they focused on defending the win. They are too focused on defending. So that Manchester United is more dominant in controlling half the field with continuous attacks. If Atalanta still played like the first half, I think Manchester United will have a hard time chasing goals. In addition, Atalanta were also carried away by Manchester United's game at a fast tempo. If Atalana is able to create their own tempo, maybe 1 point can be brought home.
