If the goal wasn't his fault, how can you say he didn't help himself much? Corner came in low and with pace; once its path changed, he was hung out to dry. The second header also had some strength behind it, so given all that you tell me how he's going to defend 192 square feet by himself?
When something happens, like a goal, it's often due to an accumulation of smaller incidents like poor covering/marking, a slip, a bad pass, etc. So I'm not saying that everyone else did their job perfectly and Pickford messed up. He just played his part in a poor goal against us.
