How to retrieve aliases from wikidata

I have attempted a query with various labels. Here just for Roma:

SELECT distinct ?subject ?subjectLabel ?nomeLabel ?cognomeLabel ?nickname ?alternative ?subjectAltLabel WHERE {
  ?subject wdt:P31 wd:Q5.
  ?subject p:P54 ?team .
  ?team ps:P54 wd:Q2739 .
  FILTER NOT EXISTS { ?team pq:P582 ?end . }
  OPTIONAL { ?subject wdt:P735 ?nome . }
  OPTIONAL { ?subject wdt:P734 ?cognome . }
  OPTIONAL { ?subject wdt:P1449 ?nickname . }
  OPTIONAL { ?subject skos:altLabel ?alternative . }
  SERVICE wikibase:label { bd:serviceParam wikibase:language "it,en,fr". }
}
ORDER BY (?cognomeLabel) 

I believe the P1449 property should be the most appropriate property to store an alias/nickname, but it does not seem to be used that much for football players. I just added "il Capitano" to Francesco Totti. Beyond that one there does not seem to be other nicknames for Roma players.

The "Also known as" label (in the right column) is not necessarily the nickname, but may be a spelling variation.

Something more generic if someone is interested in all properties that will return only the english also known as:

SELECT ?property ?propertyLabel ?propertyDescription (GROUP_CONCAT(DISTINCT(?altLabel); separator = ", ") AS ?altLabel_list) WHERE {
    ?property a wikibase:Property .
    OPTIONAL { ?property skos:altLabel ?altLabel . FILTER (lang(?altLabel) = "en") }
    SERVICE wikibase:label { bd:serviceParam wikibase:language "en" .}
 }
GROUP BY ?property ?propertyLabel ?propertyDescription
LIMIT 5000
