Honestly, I was low-key expecting Man UTD to turn the game around like they are used to doing but it's safe to say that Grimsby came all out for them I have to say that this has been the longest penalty shootout that I've witnessed in a long while and even though Man UTD tried all they could do to ensure they come out being the winners via penalties, today was just not their day. Wow, football can be really unpredictable.
In the end, Man United lost despite trying to equalize the score to 2-2, but they were unlucky in the long penalty shootout. 
Some people questioned what happened to the Man United team causing them to lose to the underdog team.
It is possible that with this defeat more fans will be fed up with the result even though it is a small tournament, the defeat of a big team still causes ridicule.
Ruben Amorim is having another setback but still few chances available for him if he is able to convert them into positive.
Their conversation is surely problem for them while too many missing chances are surely problem now next challenge is Burnley at Old Trafford hopefully they will be able to provide good result.
