Liverpool will win the premier league title this season and nothing can stop them from doing that, yes they lost to Fulham but that those not mean they are not inform no matter how strong and inform a team is in a season they will always lose a match or two in that season in the case of Liverpool losing that match those not mean they are not inform, the point gap between Liverpool and other teams in the premier league is very big and I think the reason why they even lost that match to Fulham was because of over confidence they believe the premier league title is already there own and if they don't stop that mindset it may cause them to lose the premier league.
I believe Liverpool will win west Ham because Liverpool is more inform and they will not want to lose this match again not after losing to Fulham they will do everything possible to make sure they defeat West Ham because if they fail to win west Ham and they get defeated there chance of lifting the premier league will become very small so they will do everything possible to win.
Liverpool is already a champion, a lucky champion at that. losing to Fulham was predicted because Arsenal drew to Everton and Liverpool has no title contender. Arsenal that is in second position are not giving Liverpool and tough fight for the title, so Liverpool players feels relax that is why they lost to Fulham. when you have Arsenal has you title contender just know you have the league because Arsenal has no winning mentality.
West ham is has been struggling to survive the league this season, they are 17th in relegation zone, they drew their last game against Bournemouth at home, and tomorrow they will play away against the league leader Liverpool, i still believe Liverpool might share point in this game, playing against relegation team at this stage is very difficult then when you play against top four team. Even if Liverpool lose it won't stop them from winning the league this season.
