Classically, Liverpool and West Ham are favourites. Leicester is no longer good since the beginning of the season so I won't expect much from them. Brentford showed some resistance vs top teams like a draw recently vs Spurs, a surprising victory vs City, so this match particularly is challenging.
It's true that the favorites in these 2 matches are Liverpool and West Ham United, but considering the inconsistency of Liverpool, I doubt that they can easily beat Leicester even though the match will also be held at Anfield. If Liverpool win, I'm sure it will be a win with a small score. For the West Ham United Vs Brentford match, even though Brentford has had a good performance this season, we must remember that West Ham United's current condition in the EPL standings is very dangerous, so I think they will fight harder in their match against Brentford later.
Liverpool's current condition has improved thanks to their victory, on the other hand Leicester after this holiday is still the same as at the start of the season with a team that is quite weak in terms of defense so I don't think there is any reason to doubt Liverpool at this time.
With their current condition, as well as with the conditions of playing at Anfield, this will obviously add more confidence.
