Solved it on my own. I am not sure whether this solution is the best, but I did it so:
<?php global $userdata;
get_currentuserinfo();
if ($userdata->user_level == 10) {
echo('<li>Ciao ' . $userdata->user_login . '</li>');
echo('<li><a href="http://xxx/wp-admin/post.php">New entry</a></li>');
echo('<li><a href="http://xxx/wp-admin/page-new.php">New page</a></li>');
}
?>
Bye!
