Newcastle United defender Mike Williamson isn't surprised by the success of the promoted teams this season.
Both they and West Brom survived comfortably last season to buck the prevailing trend, and that theme appears to have been picked up by both Swansea and Norwich this time around.
Williamson said: "There have been plenty of success stories like that, teams who have got promoted, stayed in the league and then built on the season.
"There's no reason why not. Swansea are a fantastic football team, Norwich have been just as good in their own way, and it does show teams can come from the Championship and excel in the Premier League."
