Since this game will start in 35 minutes I will give it for free.
Newcastle are in trouble, you can have all the money but football is more than that and right now Newcastle looks horrible, they are in 19th place but are likely to survive in the Premier League because it's expected from them in January to go to the winter market and make a lot a moves but even there, things can get ugly for them because teams need time to form a collective strenght. Newcastle had some rough games, facing Leicester, Liverpool, Manchester City and now Manchester United, these 4 games are consider their tough stretch and so far they lost the first 3 of them, scored only 1 goal and suffered 11 goals against, what is not a surprise since Newcastle is the worst defense in the Premier League.
Manchester United season in the Premier League has been tough too, only 7th place but since Ralf Rangnick took control of the team things got better, they are on a 3 game win streak and overall Manchester United looks more solid has a team, they are a bit more defensive approach because the Coach philosophy is to be more consistent on the defensive side and than built up the attack and the fact is that the results have been good this way, they aren't getting caught of guard on defense like early in the season and their attack has a lot of firepower to manage to score goals.
I think Manchester United should at least win here, they got way more secure on defense with Coach Ralf Rangnick and Newcastle so far is a complete disaster and also they are a nice prey for Manchester United who has beat them the last 4 games with 15:4 in goals. I see Manchester United winning here by 2:1, 3:1 or even 4:1 they way Newcastle is defending Manchester United attackers should have no issues to create many scoring chances, it's just a matter to take care of those chances.
