I also expect Arsenal to win tonight. Arsenal are on a good momentum right now and have far better quality than West ham. With Liverpool leading the table temporarily Arsenal will target to get the 3 points desperately and be on the front seat again on the table. Hammers are a tough opponent as they have some good players so Arsenal might have to be wary of their attacks.
Spurs have some injuries so I am not entirely convinced but considering their performance they should be able to get some points. Yes, I also wouldn't be surprised if Brighton also comes out to win the match as Spurs lack their regular players and might wobble a bit for the time being.
Injuries is the major threats most of these competitive elite clubs faces, because once their keyplayers is injured, we have nothing interesting or hope for because these elite clubs performance will definitely declined. Mikel Arteta knows the tactics he would implement if he wants to win top matches. We become very competitive and interesting when our favorite clubs have fixtures to play. Arsenal taking home three points without doubt but where we have problem is the Brighton vs Tottenham Hotspur. Both clubs keen on winning the game tonight, if we're placing our wagers, we just have to become very careful and smart when dealing with these matches.
