This season, Liverpool have dominated the Premier League (which was dominated by Manchester City just one or two seasons ago) and they also dominated most of matches they have played in the league so far.
Liverpool also dominated the league last season with a point lesser than the champions.
Liverpool had a lucky match, definitely, to win at the end but generally they deserved that win with support from their luck.
West Ham was unbelievably just unlucky and LFC is still with a strong determination to maintain an unbeaten record at EPL.
I wouldn't necessarily call it lucky or not but instead have to point to both goalkeepers for making it easy for their opponents to score such goals...
- On a normal day, the scoreline would have been a 1-1 draw.
