Custódio could end his wait for an international cap at the age of 29 when Portugal take on Turkey in their final Euro 2012 warm up match on Saturday.
The midfielder has had to remain patient throughout his career in his homeland as well as a spell in Russia before gaining the call up for Poland and Ukraine.
He helped club side Braga reach last season’s Europa League final, scoring their winner in the semi-final.
Having played for Sporting Lisbon and Dynamo Moscow, Custodio knows all about pressure but he appears to be relaxed about trying to help his country go for glory.
Speaking to UEFA.com about his call-up for the championship, Custódio said: "I was at home with my wife and kids. They all jumped on top of me. It was like I'd just scored."
After the match in Lisbon, Paulo Bento’s side will get ready for their opening game of the tournament against Germany on Saturday 9 June.
