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
I think Arsenal will soon turn things around and win because their dominance is very strong in this match. It's just that their execution was too slow and it's true, Wets Ham was really able to take advantage of opportunities that, even though they were small, could be really effective. Arsenal are already 0-2 behind West Ham and it is now the 82nd minute. So, it will be quite difficult for Arsenal to take over. unless their trainer can make something happen unexpectedly. but this seems quite difficult.
