If there's one thing we've learned about the Premier League, it's that promoted sides often find it tough to stick around for more than a year.
Since the 2017-18 season, when Newcastle, Brighton and Huddersfield all stayed afloat, at least one promoted club has gone straight back down.
Last season, Norwich and Watford failed to preserve their status, going from top two in the Championship to bottom two in the top flight, though Brentford's survival ensured it wasn't three from three.
