I've watched all of his goals. I was present for many of them. Including his debut at Wimbledon. For a relatively short player he certainly did score a decent amount of headers, he had a decent leap and lovely technique, but let's not pretend that the vast majority of his goals, 90% say, were NOT scored with his head.
And as for his long-range shooting, he didn't exactly thump many in from 25 yards or free-kicks, he was no Fowler, Shearer or Henry in that regard.
But he was a brilliant striker and one of the very best to ever play for Liverpool
