1.) His defensive Positioning in heading is just poor, only 55% of won Headers is for a CB just weak and a result of his Positioning.
2.) 61% of won direct duels on the Ground is average, nothing more, for example: Per Mertesacker in a average Season so far, won 70% on the Ground and 75% in the Air.
On my Point of view is Geromels archievement average and legitimates surely not a 84
Maybe something to discuss?
A good indicator for his partially poor Positioning was the wrong timing when he was initiating a offside trap against Wolfsburg yesterday.
