Heading a ball like Gestede did was purely down to desire to win the header. Same as tackling was to Stuart Pearce, Ron Harris, Roy Keane or Norman Hunter. Yes there are degrees of competency. But that's the first base. You don't have that desire the rest is irrelevant. Gallagher is a big lad, a proper athlete and there's a good reason he gets linked to Boro and the likes. The raw materials are there. In my opinion, he's too nice.
