I actually didnt realise that. He goes up in my estimation in that case given he's managerial education is broader and he's actually won things (as well as playing good football, despite average players). There's plenty of managers who have done 'something' in lower league English football, but regular promotions in an unfamiliar environment speak more to a manager's capabilities. For me, that puts him close to Rodgers and Nagelsmann as options...
From wiki:
In December 2010, Potter signed a three-year contract as coach of
Östersund, who were then playing in the fourth tier of Swedish football, starting on 24 January 2011.
[11] Potter was offered the job after
Graeme Jones, his friend and assistant to
Roberto Martínez at
Swansea City, recommended him to chairman Daniel Kindberg after their pre-season friendly with Swansea.
[12]
In 2013, after two successive promotions, Potter extended his contract with the club for another three years.
[13] On 27 October 2015, Östersund secured promotion to the Swedish top flight,
Allsvenskan, for the first time in their history following a second-place finish in the
2015 Superettan.
[14] Östersund finished their
debut season in eighth place, winning plaudits for their "slick passing game" and competing on a limited budget.
[15][16]
On 13 April 2017, Potter's Östersund team won the
Svenska Cupen, beating
Norrköping 4–1 in the
final.
[17] This granted the team a place in the second qualifying round of the
2017–18 UEFA Europa League where they defeated
Galatasaray 3–1 on aggregate.
[18] In the third round they defeated
Fola Esch 3–1 on aggregate
[19] and in the play-offs they knocked out
PAOK (3–3 on aggregate with more away goals), thus securing a historic entry into the Europa League group stage.
[20][15] They finished second in their
group, level on points with
Athletic Bilbao.
[21] Despite beating
Arsenal 2–1 at the
Emirates Stadium, they were eliminated from the competition after losing 4–2 on aggregate.
[22] Östersund finished their
domestic league season in fifth place.
