Rijeka have won their 1st ever title in Croatia and ends an 11 year title run by Dinamo Zagreb. There is still one matchday to go and Dinamo actually host Rijeka so it would have been interesting to see what kind of weird stuff would have happened if it was a title deciding match.
Partizan won the Serbian league over rivals Red Star after turning a 3 point regular season deficit into a 3 point advantage in the championship playoffs. Partizan went 7-0 in the playoffs including a win at Red Star.
Most champions have already been crowned around Europa although there are still some undecided;
In Turkey, Besiktas holds a 4 point lead over Istanbul Basaksehir with two games left. Both teams play bottom feeders to close out the season so looks like Besiktas will have a good chance to repeat as champions.
Poland has two games left as well with as many as 4(!) teams still able to win it. Legia (40) are in the lead with Poznan, Gdansk and Jagiellonia (all on 38) right behind them. The top 4 will play the bottom 4 in the next round, the final round will see Legia host Gdansk, while Poznan travel to Jagiellonia.
In Hungary, Honved and Videoton are tied at 62 pts with one game left. They will play eachother on Saturday in Budapest in what's basically a gold medal game. Not sure what the tiebreaking procedure is. Honved have more wins but Videoton has the way better GD.
Ferencvaros, who won the league by 21 points last year, will likely only finish 4th.
In Bosnia, Zrinjski (61), Zeljeznicar (60) and Sarajevo (59) play the 4th, 5th and 6th placed teams on the final matchday.
In Montenegro, Zeta (57) and Buducnost (54) both have their final game at home against clubs who've already been relegated.
And finally, the final matchday in the Czech Republic will see leaders Slavia Prague (66 pts) host 11th placed Zbrojovka Brno with a chance to win their first title since 2009. Second placed Viktoria Plzen (64 pts) winners of the last two championships, host 14th placed Vysocina Jihlava and have to hope Slavia slip up for a chance at a threepeat. In case of a tie at the top, Viktoria Plzen will be champions based on their better head to head record against Slavia.
