@Egemen Deliorman, it's best if you provide us with the original sources in the future, i.e. the ones in which the background hasn't been removed.

I downloaded this photo from beinsports site.

The one on the beinsports site is 512x512.

The one you uploaded was put through remove.bg:

The only thing I did was to remove the whiteness. I don't think it's a big problem. Anyway, I hope another member can help.

And I'm asking you not to do so in the future 👍

I'm sure it'll be cut soon, don't worry.
