Even though they are playing at home, West Ham will find it difficult to find winning points against City. City have a very productive attack line. In 4 matches they have scored 11 goals. and they are not yet defeated. If West Ham can hold a draw in the next match, that will be a good achievement for West Ham.
City is West Ham's first tough opponent this season. they have to fight hard to show improvement in their game. This is not easy but it is still possible for West Ham if they implement the right strategy to contain the aggressiveness of City's attackers.
Because a home stadium is not enough for West Ham to cover big difference in quality between their squad and Manchester City squad. Manchester City so far have very hot streak in early of Premier League season. West Ham have to prepare best for the match and hope that Manchester City will be affected by their international duties last two weeks. If star players of Manchester City start the match without 100% fitness and feel tired, West Ham will have better chance to get a point in the match. I don't think they will be able to get three points from Manchester City.
At the start of this season West Ham also performed optimally by getting 3 wins and 1 draw so they were able to occupy fourth place with 10 points the same as the second and third place winners who only had 10 points.
Today home match will not make West Ham experience an easy match because Manchester City will definitely hunt for victory to be able to secure full points and be able to save 15 points later.
The advantage still belongs to the Manchester City squad and it looks like a 1 - 0 or 2 - 1 win will happen later.
Manchester City is currently on top of everyone in the table and they are still unbeaten in this season. So surely it is not going to be easy for anyone to beat Manchester City. And Manchester City have not shown many weaknesses this season. So I don’t think there will be much exploitation from the opponent.
They have weakness but it's just challenge for their opponents to be strong enough and play cleverly enough to exploit weakness of Manchester City. Their opponents must have good tactics, good ability to follow initial plan and keep calm during a whole match, because Manchester City players only need one or two moments to decide a match result.
Of course every team has weak points but Manchester City has the greatness of covering their weaknesses so that opponents cannot see or read what they should do and how to find loopholes for Manchester City weaknesses.
So far Pep has worked very well and is able to fill or cover Manchester City weaknesses so that opponents cannot know what their weaknesses have been.
West Ham coached by David Moyes doesn't seem to know what Manchester City true weaknesses are and I'm sure West Ham will still experience difficulties that might prevent them from being able to do much or play optimally.
