Opinions on these players...

Looking at signing a couple these players but want your opinions on them first e.g your experiences with them in general

1. Julian Draxler - Noticed, although young, his mental stats are quite low- does he develop well?
2. Isco - Good stats but heard alot of criticism about him
3. Thiago Alcantara
4. Paulo Sarabia
5. Christian Eriksen
6. Marco Veratti
7. Stephen El Shaarawy
8. Bernard
9. Granit Xhaka
10. Ruben Pardo

I'm at Chelsea and can't decide which ones to sign so your opinions will help a lot :)
