link to profile in menu
You can use the link directly as /user. It also goes to the profile page which is similar to the /user/{$GLOBALS['user']-&gt;uid}
Now if you want user id also with it, e.g profile in edit mode (user/10/edit) then you need to add Menu Link module. It provides  you option to use Token to make the link dynamic for every user profile instead of static path.
Hope it will help.
