because as above, you don't actually change the number of goals to "count double" on the scoreboard, you do the math in your head and say "team won on away goals"
Technically, the score would be 6-5. The actual score on the scoreboard would be 4-4 with Sunderland winning on away goals.
It's hardly the massive error that some people are suggesting.
You can tell we aren't used to this away goals malarkey.
