#2 and #4 are resolved for Slovan. Regarding #3, it was in the news today that Slovan's new owner Hrubý met with the mayor of Bratislava in order to discuss paying the debt for the arena left by the previous Slovan ownership, reported to be €600,000 this time around, I think. They said it was a good meeting, so in all likelihood, all debts will be paid and the arena will be available for Slovan in future seasons. And unlike with the previous owner, Široký the oligarch, I don't think the new owners will permit Slovan to accrue new debts.
The biggest stumbling block would be #1, of course, but if the oligarch managed to do it for 7 seasons, so should the new owner, reported to be six times wealthier (and having earned that wealth in upright software business).
Naturally, there is no clue as to whether the new owner is interested in the KHL at all. But, given that his first step was to rehire Krejči, Slovan's general manager from its KHL seasons up until 2017, it at least seems to be a possibility. We can only hope so.
I'm just happy it wasn't the guy from Banská Bystrica, the optician (iClinic), the owner of Bratislava Capitals, due to play in EBEL next season, who ended up buying Slovan. It was reportedly a very close call. The iClinic guy was basically already giving interviews as Slovan's new owner, but then everything changed. Fortunately! Because in those interviews, he made it clear he thought the KHL was a bad idea for Slovan, and that Slovan should play in the Slovak league. While, he admitted, the main reason for Bratislava Capitals joining EBEL was so that he can advertise his opticians' business in Austria, using the hockey club, which is otherwise severely limited by Austrian laws.
If the ideal scenario one day occurs – Slovan back in the KHL, Slovan "B" (farm team) in the Slovak league, and Bratislava Capitals in EBEL – it will be interesting with the arena. Can it simultaneously host 3 hockey teams playing in 3 various leagues? Perhaps. It will be co-hosting Slovan and the Capitals in the upcoming season, so 2 teams and 2 leagues are no problem, but adding the KHL on top of that might be difficult.
(Too bad Bratislava did not build a brand-new hockey arena, as it was originally supposed to prior to the 2011 World Championships. That's what you get when both your country and hockey association are ruled by oligarchs... Well, things have changed dramatically for Slovakia in 2020: there's a new anti-corruption government, Šatan is the new hockey president, and Slovan has a new owner. Let's see what happens!)
