Unfortunately, goalkeeper only need 1-2 games to haunt him forever, particularly if it was a Champions League Final, or a mistake that cost the team dearly, with our press forever reminding us & him, just like how hard they tried on DDG's previous mistakes. We are still reminded by TV and press, of the Spurs goal that should have been registered.
Striker on the other hand, can walk away from 1-2 bad games and score a handful in the next one.
i.e. If Henderson repeats another howler like he did at Burnley, he should be sold, before he end up like Pickford.
