Gunnarsson, Arter, Camarasa. Gunnarsson and Camarasa are undroppable after the last couple of games so it's a toss up between Ralls and Arter. My initial thought was Ralls, as he's more capable of finding the net, then I discovered that his pass success rate is the lowest of all our centre midfielders (Arter's is the highest, though Arter is someone who plays a safe ball more than Ralls, who is a more adventurous passer).
