Looking at the goals again - link:

First: No chance, Willock lost his man at the front post for the short ball and couldn't get through the crowd to the back post in time. Also made a great save from the exact same thing happening beforehand.
Second: No chance, one on one from the halfway line with no centre half cover. Striker maneuvered him into the middle of his goal and placed it well into the bottom corner.
Third: Another tough one as placed into the side netting in the opposite corner. Putting this on him would be harsh.
Fourth: Another one that was a one on one from the halfway line and he visibly loses his footing on the penalty spot leaving an easy chip over him for the striker.
Fifth: This is the only one I think blame can be apportioned and even then I don't think it's critically on him. He's facing an incoming winger pushing onto their stronger right foot going across goal but because he's going so far across he's got no choice but to move into the centre of the goal and it's well placed to the side he's moving away from. Maybe a little bit of blame as he's flat footed but equally it's a well placed shot and more importantly a well timed shot from the winger.
I think anyone giving him serious doubts after this game is being a bit harsh really. I know conceding five makes it look like the keepers had a shite game but he made more good saves than mistakes leading to goals against Mansfield and more crucially the entire team was on the beach or nursing serious hangovers - if they were old enough to drink that is.
