West Ham have been solid in defence so far this season.
Since their defeat to Man City, they have conceded only two goals in five games in all competitions.
The Irons have managed to demonstrate they are a strong defensive force with the likes of Sebastien Haller just itching to find the net.
They have been tipped to challenge
They face a United side who scraped passed Kazakhstan's Astana at Old Trafford 1-0 on Thursday.
We caught up with Andy Ha who gave us his thoughts on this weekend's match:
Win, lose or draw?
West Ham have a decent home record against Manchester United, and given the injuries which Ole Gunnar Solskjaer's side have, the Hammers should be confident of a positive result. 2-0 win for West Ham.
The Irons are 21/10 to win and 16/1 to win 2-0 .
First goalscorer?
Sebastien Haller was unlucky not to get anything from the Aston Villa game, but he can back up his excellent form before that with another goalscoring performance on Sunday.
The summer signing is 5/1 to score first .
First card?
Declan Rice. The midfielder has a foul in him and if United play their counter-attack effectively, it could be an ugly mixture with Rice ending up in the referee's book.
Over 3.5 cards is 4/5 with thepools.com. So just absorb this key stat. In his last five matches referee Anthony Taylor has shown five, six and five yellows, six yellows and one red and EIGHT yellows and one red.
Who is on penalties?
Mark Noble. The West Ham captain is 17/4 to score anytime .
Will you keep a clean sheet?
United could lack the quality to trouble West Ham, with Paul Pogba, Anthony Martial both out and Daniel James a doubt. West Ham have kept two clean sheets in a row and could make it a well-timed hat-trick.
The Irons getting a third clean sheet is conveniently priced at 3/1 .
