I know this is a week late given the season has already started, but still thought this was worth posting. Below are the details of the number of points Swansea won by opponent, ordered by the final league standing.
Swansea won 25 points against the top 10 sides and 22 against the bottom 9. Only Man Utd, Everton and Norwich did the double over Swansea, with the Swans taking 16 points against Liverpool, Fulham and West Brom who finished 8th-10th.
You can't pick and choose where the points come from but the wins against Man City and Arsenal that there's no-one out there to fear.
