Looking at the composition of the players and the formation of the two teams in this match it looks like they want to play openly now.
Crystal Palace will play quite bravely in my opinion because they use a 4-3-3 formation with Zaha, Mateta and Ayew spearheading them.
On the other hand, Arsenal still make Lacazette as their target man in the barge by Odegard who became the second striker there.
With this formation, it seems that Arsenal want to slightly secure their midfield by placing 5 midfielders.
Although in fact Emile Smith Rowe is also a player who is as good or maybe better in terms of goal statistics, but Martinelli looks special for Arteta to play. But that's just my wish because Arteta knows better what he has to do for today's match, and I'm sure Arsenal will win and snatched his position again from Tottenham.
