Mike Johnston said:First winter Arctic Warbler (borealis) might be the only other possibility, but I don't think so. Eye-stripe/lores would be darker, ear coverts blotchier, flanks not as clean. It could be nitidus - it just seems more likely to be a young trochiloides. Colour could be to do with the light and the yellowy vegetation.

Which was actually the feature I struggled with, when sorting this borealis out.
May still not be conclusive though.
Plumbeitarsus (Two-barred Greenish Warbler) would normally have a more strongly marked wing bar up to the scapulars, and a second wing bar on the median coverts.Askar Isabekov said:Dear all.
There are no nitidus in Kazakhstan (Please see list of Kazakhstan Sylvidae http://www.birds.kz/index7.html#SYLVIIDAE ). This birds may be viridanus or plumbeitarsus only.
Like so it is plumbeitarsus .
Thanks all.
