SQL & PL/SQL

I have created table in PL/SQL stored procedure by using the below code

EXECUTE IMMEDIATE 'CREATE TABLE USER_STATS(ID NUMBER , ADDRESS VARCHAR2(1000), DOB DATE)';

Now i want to Grant SELECT on for a user

EXECUTE IMMEDIATE 'GRANT select on USER_STATS to User_Sch&&INDEX._Sel_Rol';

But i have got the below error

ORA-00911: invalid character
ORA-06512: at "User_Sch01.USER_PACK", line 7
ORA-06512: at line 2

Please guide me to give the Grant for the table using execute immediate statement.
