Not rooted but not stood in no mans land like Timmy used tooYou don't keep central in that situation though. You protect the near post. Look again at 0:41. That header was not hit 'bang central'...it is closer to the near post.
That goal is on Baines for not blocking the cross and Holgate being late and Lamela beating him to the ball.
You clearly don't know a thing about keeper positioning. A bit like @Joey66 who thinks a keeper should be rooted to their line when someone shoots from 30 yards.

Their goal was coming yesterday the first time we tried to pass our way out of defence and bang we concede!
