It's really boring to watch the match, both of the teams play defensively and pass to each other. I consider it's lucky because Manchester United didn't play good enough and the goal scored by Martinez is come from out of nowhere.
But, with this win, it makes Manchester United away from entering relegation zone.
Tottenham now really in bad position, I don't know why Tottenham still not firing Ange Postecoglou for make Tottenham to be like this bad.
I completely agree, the match was really tough to watch. United looked far from convincing, and the game felt more like a scrappy battle than actual football. Martinez’s goal after the deflection was pure luck rather than the result of a well-crafted attack. The team created almost nothing throughout the match, and this result feels like a gift from fate. But, as you rightly said, this win helps Manchester United move a bit further away from the relegation zone, which, at this point, might be the only positive takeaway from their situation.
