Setien always keeps on changing the attacking player positions so he will atleast find someone to replace in next two matches. They have young player Ansu Fati, new signing Martin Braithwaite and even sometimes he rolls down Vidal in attacking line. They have plenty of players who have played in the usual formation Setien rolls so they are kinda bit adjusted with it.
I think Fati will be one starting in next along with Mesi and Suarez in attacking line. He was out from suspension in previous one. Tho can't say for sure.
