I dunno there is some pretty strong competition now in Ukrainian League. Dynamo Kiev are finally looking like a good team after 3-4 years of underperformance. Yarmolenko, Milyevsky, Kranjkar, Admir Mehmedi, Miguel Veloso are all good players. Now they have Blokhin in charge they could push on and make a challenge to Shakhtar (although its really messed the Ukrainian national team who are now manager less).
You also have second level teams like Dnipro and Metalist Kharkov, who are again building strong teams with good young players. Dnipro have Inkoom (Ghana center back signed from Basel), and have also signed the Croatians Kalinic (striker) and Strinic (defensive player). They also do well by signing players that Dinamo and Shakhtar sell too early - Vitaliy Mandzyuk, Kravchenko and Gladkyi are all from the big two and now they have Oleksandr Aliyev too from Dinamo. But their best player is undoubtedly Konoplyanka who is the rising star of Ukrainian football. Metalist have a lot of talented South American players, like Jose Sosa (ex Bayern / Napoli), Taison and Cleiton Zavier, and Papa Gueye, who was very impressive for Senegal in the Olympics.
You say the league has no competition, but I dont think it's quite the case. Certainly teams like Metalist and Dnipro have done reasonably well in the Europa league over the last few years - Metalist got the quarter finals last year, defeating Olympiakos, after topping their group, the year before they came second (behind PSV but above Sampdoria) before going out to Spartak, two years earlier they topped a group with Benfica, Olympiakos, Galatasaray and Hertha Berlin. This year Dnipro have already beaten PSV, and Metalist have have drawn away in Leverkusen.
