Fred definitely did not look like prime Fabregas in Ukraine. He looked similar to how he plays here, but more effective in the worse league with a lower average level of technique/athleticism. As rnd suggests, he was able to look a better ball carrier and was slightly tidier, but still not to the level that he was a consistent creative player in the team like Fernandinho was able to be in his time there. His partnership with Stepanenko was very much two workhorses, with Fred the better player of the two, as he was more athletic.
I'd say he was around the same level as his teammate Bernard at the time; good important player for them, obviously enough there to try and make a step up, but not really playing with the sort of consistent dominance/talent where you can see they entirely outgrown that 6-10'ish ranked league level and are excited as a neutral to see what they can do in a top 4/5 league. Ismaily, Srna, Alex Teixeira, Douglas Costa (though he was still quite inconsistent) are the players in that team i think were closer to that, with Marlos and maybe Taison also at least as good/important as Fred, though they were 4-5 years older, while Fred was just entering his peak during his last season or two.
Mudryk is massively less experienced than Fred was when he moved and played his domestic football while the league is at a low point for obvious reasons. Obviously he was bought for his performances and potential shown in the european games, but in terms of the overall standard of football he is usually in, it's a bigger jump in class than it was for Fred, or the likes of Douglas Costa, Willian, Mkhitaryan. Ukrainian league was closer to the Portuguese league in standard back then, and in that bottom half of the top ten coefficient bracket for a long time, but now it's closer to 20 and has lost a lot of talent.
