Galatasaray is so slow with their transfers man... Ugochukwu is the only signing so far right? There are many other speculations but no concrete moves yet.

Can Uzun, Reijnders, Ødegaard and many more are rumoured... Can Uzun for the number 10 role would be nice. But if Arsenal is keen on selling Ødegaard then we should prioritize him I think.
I agree with you. I don't like how slowly Galatasaray are moving in the transfer market either, but there's not much we can do about it.
To be honest, I don't even know who they've signed so far, or which players they're seriously linked with. I only know one or two names, and that's about it.
In my opinion, Beşiktaş have been the most successful club in the transfer window so far. Fenerbahçe are also working on strengthening their squad, but Galatasaray seem to be the furthest behind at the moment.
