This is exactly what West Ham are doing, with possession of the ball for the entire 25% they lead 2-0, I doubt that Arsenal will be able to win back to a draw, but so far 75 minutes and with such pressure they can probably do it, the main thing is to score one goal, and there on the psychological pressure will be able to score a second one
Arsenal could not hold Westham to a draw less a win for them. Arsenal will remain in second place below Liverpool who are topping the table now. It was a game well played by Arsenal but were just unlucky not to have scored any goal in all the 90 minutes of play. West Ham had their chances and they were able to convert them to goals instantly. West Ham will remain on 6th position and continue their fight for the top four of the table. The table and point difference from number three to six looks so tight and anything can happen at anytime.
