#3 West Bromwich Albion's physicality overwhelms Manchester United
Apart from a double chance Manchester United were presented in the 70th minute, West Bromwich Albion thwarted the visitors on almost every other occasion.
The hosts maintained their positional discipline and defended with gusto to keep their more illustrious visitors at bay.
Allardyce's side forced Manchester United to play the ball out wide, which explained why Rashford and Martial did not see much of the ball in the West Bromwich Albion box.
Manchester United, though, had a penalty that was overturned because Harry Maguire was apparently off-side. Otherwise, West Bromwich Albion also thwarted the visitors from breaking through the middle.
#4 West Bromwich Albion could have taken all three points
While West Bromwich Albion's struggles continue, they'll take a host of positives from their draw against Manchester United.
They were the superior team in the air both defensively and offensively. Manchester United played second fiddle for most of the match.
It was a performance typical of a Sam Allardyce side; solid at the back and blistering on the break. However, Manchester United lacked the urgency and accuracy with the final ball.
West Bromwich Albion came close through Robert Snodgrass in the first half. But the former Hull City winger's header was tipped over the bar.
Diagne then fluffed his lines off a sensational cross in the 88th minute, while he also saw his effort saved by de Gea in a one-on-one situation.
Manchester United can consider themselves a tad fortuitous that they could eventually force a share of the spoils on the night.
#5 Conor Gallagher is coming of age for West Bromwich Albion
It was a sensational performance without the ball and on the break from West Bromwich Albion.
The team's defensive application ensured Manchester United were out of ideas, but one player whose all-round display caught the eye was Chelsea loanee Conor Gallagher.
The 21-year-old was a complete package in the Baggies midfield. He sat deep to block the channels and intercept longe passes; Gallagher also impressed on the ball whenever West Bromwich Albion ventured forward.
In a system like West Bromwich Albion's, it's essential for a midfielder to have quality and creativity on the ball. Gallagher demonstrated both of the attributes with a delightful cross for the opener; he also showed his intelligence to drop into deeper positions when required.
The Chelsea loanee is one to watch out for the future, as he isn't afraid to break into dangerous areas and let fly from distance as well.
