Vs Spurs - 1.43 xg vs 0.83
Vs Brentford - 4.47 xg vs 1.6
Vs Fulham - 2.22 xg vs 0.34
Vs palace - 2.5 xg vs 1.08
Vs Leeds - 1.89 xg vs 1.66
Their only bad performance in those 5 games was vs Leeds where yeah it was a fair draw. They outplayed every other team and got fecked by the refs in multiple actions vs Spurs for example or just had some bad finishing and clinical opposition finishing, conceding 2 goals from 0.3xG for example.
Oh and before you say "maybe they just can't finish chances like top teams", United is underperforming their xG by more than Brighton is this season.
They are an excellent team really, and performance wise, expected stats wise (which essentially rates how well they create and prevent chances over a season), they are the 3rd best side in the league. They have their weaknesses as well they have a mid table squad mostly and a mid table budget, but as a team, the way they play, is that of a top team. Things like keeping the shots out in the key moments or finishing the chances you create they lag behind.
