Free agents who still have not signed with a club yet:
-Dani Alves
-Danny Welbeck
-Daniel Sturridge
-Juanfran
-Fernando Llorente
-Mario Balotelli
-Franck Ribéry
-Claudio Marchisio
-Nico Pareja
-Gary Cahill
-Martín Cáceres
-Hatem Ben Arfa
-Nemanja Radoja

These players are still relevant to some extent and clubs have not signed them yet and we are closing to the end of summer window transfer, what could be the reasons?
