Dukla Praha with Pluskal in its line-up won the "American Cup" (a tournament of teams from football-developed countries) three times in a row in the first half of the 1960s.

Losing 1–0 to Northern Ireland, drawing 2–2 with West Germany, and scoring a remarkable 6–1 victory over Argentina, under modern rules they would have gone through.

Thanks to Pluskal, the team that had had to qualify for the Championships in a playoff with Scotland had got to the World Cup final.

In 1965, Pluskal played in the unsuccessful qualification campaign for the World Cup in England, but with this his international career ended.

[2] Thanks to his important contribution to the success in Chile, Pluskal received recognition on the international stage.

On 23 October 1963, he was a member of the "Rest of the World" team that took on England at Wembley in front of 100,000 fans, to celebrate 100 years of English football.

He did this job for Plzeň clubs Škoda and Slovan, later on for FC Bohemians Praha and for a few years in Enosis Neon Paralimni of Cyprus.
