I think this week will end really badly for Manchester City. Because I believe Liverpool, Arsenal and Aston Villa all are in a situation to be able to win their games this week. Liverpool can win against Manchester United home easily while Manchester United are bad at defending. Arsenal should be able to beat Brighton home as well.
Aston Villa are playing an away game against Brentford but Brentford are really bad this season. They were able to win only once on their last 5 game weeks in the league. I don't think they can hold off Aston Villa from winning another game.
Even though Manchester United's defense is considered weak in my opinion, this will end in a draw from Manchester United's performance in the last few matches which continues to experience inconsistency in every match even though they just suffered defeat last week and in the Champions League, in my opinion Manchester United will correcting and evaluating their previous game, even though they have to face Liverpool and getting points seems to be difficult at least with a draw it would be much better, even though it sounds like they don't have optimism in running their match..
It looks like Arsenal and Aston Villa will win easily because they only have to win the match, if Arsenal loses then Arsenal will be in 3rd place in the standings, in fact if Astom Villa wins the match then they will move up in class, if both lose then nothing will change from the rankings perhaps Man City will move to second place in the standings and both Arsenal and Aston Villa will be knocked out of their current standings.
Manchester United's performance is currently quite poor after a series of unsatisfactory results they have received since the start of the season, but the match against Liverpool is a prestigious match because of the rivalry between the two teams that has existed for several years.
So even though Manchester United is in a slump, it is not impossible that in this match they can come out and rise to match Liverpool's performance.
I think in football anything is possible.
