Arsenal struggle against teams that defend and look to counter attack so I do not agree with 80% I think they are favorites and should win the game but I am always nervous against Crystal Palace because they are very good at defending and getting wins by scoring on the counter attack which is our weakest point in the team. I do not think it is worth betting on this game unless you are going for Crystal Palace to win because Arsenal are too risky to bet on to win without any big return
Martinelli has made Arsenal ahead with one goal so far, this time Crystal Palace's defense is not as strong as in other matches. It can be seen how Arsenal can enter the goal area several times to attempt shots, quite sure Arsenal will win this match because Palace is playing quite under pressure at home to the opponent.
