Header can be 82 , because he do 2 goals this way and looks like a shot or a punch and not a header . I very happy with the directors of Gremio for buy a center back on same level at Rever. He makes the kind " sheriff " and have a face
He is, of the Gremio's players, what else needs adjusting.
He has good positioning, good response, great tackle. But the areas that need more changes are Mentality, Teamwork and Jump, IMO. He was hired to be the leader of the defense and soon supplanted Rafael Marques (a good center back).
Look at his jump when he makes the first goal (the defenders that day were Bolivar and Sorondo from Internacional, which are taller and has 84 at Jump):
I suggest to those who watch the game tonight against Santos, then we can evaluate it together.
