It was an important win for West Ham after a long break. The situation was the same for Everton as well but they couldn't do much in this game.
I was actually surprised when I saw the odds first. Because there was a huge gap as West Ham were favoured too highly to win this game. It looks like bookmakers knew what they were doing. There wasn't much difference between these teams in the league actually. Their positions in the standings weren't very different. Lampard is getting close to the end of his time at Everton.
