I had to laugh a couple of seasons back when some of the americans were concerned about a club from Saudi or the Premier League (I think Everton, in particular) would come knocking for him, and the talk of him getting a Wales call-up.
Luton spent four seasons in League Two and four seasons in the Championship. They were promoted from the National League in 2013/14 and from the Championship in 2022/23.
Bournemouth hadn't been lower than League Two equivalent since the 1920s, so couldn't really do it anyway, but even then they spent three seasons in League One and two in the Championship.
