Chelsea is winning this match with ease, If you rate Chelsea performance against Crystal palace, to me Chelsea was very lucky to draw in that game, because Crystal palace outplayed them, is not Chelsea performed poorly, its just that crystal palace is a team to beat in this league, they have a solid team.
Today game against West ham will not be so hard for Chelsea, Chelsea is going to beat west ham with high margin of goals. If you are staking , give Chelsea over 2.5 goals. All the goals they did not score against crystal palace they will score it today. There is nothing to worry about in this game.
If we look at the previous match, it can be confirmed that Chelsea against West Ham can be predicted that Chelsea will be able to outperform its strength, but the potential for a surprise given by West Ham's resistance can turn things around, even though West Ham is currently without player Crysencio Summerville because of an injury, it could make their game less complete even though there is a replacement. Of course, that could hinder the team's desired advantage.
