Playing firmino onside was a shocker although I dont know what the defense was doing with a line quite that high in the circumstance - Blind was coming across and toward our goal to cut out a cross, still should've stepped by quicker.
The more he plays at centre back the more the issues with his strength and height seem exaggerated, he rarely gets shoved off the ball or beaten in the air, yes it happens but it does for every defender.
That's only because he challenges for headers and phyical battles less than pretty much our any other player.
