Jonasson won't do a full season in the UK, surely.
Lebedevs might, he's back at Lokomotiv Daugavpils in the Polish Nice League 1 and after winning the SEC in 2017 had a poor season last year. No idea what his average would be.
Did the same for 1991 final at Gothenburg, I guess back in the days of the World Final it was an annual pilgrimage for allot of Speedway fans and it was for a large part before the internet made organizing a trip so much simpler.
Only Woffinden (Ekstraliga), Lambert (Nice 1) & Lawson (League 2) did enough meetings in attain an official average in Poland last year of the British riders. Which I assume is 7 meetings. Bewley (5) & Cook (4) didn't do enough meetings in League 1. R Worrall (5), Wright (4), Ellis (2) & S Worrall (1) didn't do enough meetings in league 2.
Aussies of similar standard to those Brit's Grajczonek, Tungate & Masters (Nice 1) and Morris (League 2) all did enough meetings to attain an average.
Falubaz have got a stronger top 5 than Leszno in my opinion but Kubera & Smektala at reserve mean Lezsno will score points from top to bottom, unconvinced Wroclaw will make the playoffs. But it does look like being a tough year for Lublin.
Furthermore, I assume the organisers actually hope visiting fans will attend these events. More likely to get a German or Latvian spectator at an event in Poland than an event Manchester.
Finns & Swedes would probably have to fly to either UK or Poland, by contrast Latvians, Germans, Czechs, Slovaks, Ukrainians can drive to Poland relatively quickly.
Driving to Poland from Italy, Slovenia & France would be more of a journey.
Well the other semi will surely be in Poland. So, economically it would make sense for the other continental teams to contest that - Poland, Germany, Denmark, Latvia, Czech certainly. Australia, Sweden, USA, France & Finland likely to be at NSS. Unless they really mix it up.
