This is why I think the lack of a strong captain is a big factor. The buck stops with Wenger, obviously, but IMO that is a big factor.
That said, the players don't get off the hook entirely. If you're 2-0 down to Watford in the FA Cup then maybe you should get going earlier than 5 minutes from the end. If they'd switched on 10 minutes earlier then we'd have done no worse than get a replay.
