Nuno Espirito Santo sprang a surprise on Monday when he switched from a back three to a back four for the first time as Wolves head coach.
So how does that shift the dynamic in terms of what we should expect from them on Sunday?
“Obviously it is different and you could see the way they finished the second half in the last game [against Southampton],” Mikel Arteta said.
“We know we have to be prepared to go against both situations, in the back three formation they have different options to play as well and they are threat in different areas, so we need to get prepared like we always do.
“[It is] a really tough game, they are one of the most organised teams in the league for sure.
“They have been together for a long time, they have shown in big games against big opponents how difficult they can make it so I am expecting a difficult game against a team that dominates almost every aspect of the game I would say. They know exactly what to do.”
