That's on a different level of prediction. There are lines for Arsenal scoring first or winning the first and second half. There's also a line for over 3.5 goals so why not try your luck and bet on your own prediction. Good luck.
I think Crystal Palace scoring 1st is the best odds because Arsenal struggle to score against teams that defend and counter attack quick and our defense is not the best against counter attacking teams. If you look at most of the goals Arsenal have conceded this season a lot of them are through counter attacks because our defense are always high in the field and we do not have the pacy defenders that other top teams have and Crystal Palace are very fast in attack.
