Marcelino lauded Athletic Bilbao, who will contest two Copa del Rey finals within a fortnight after overcoming Levante on Thursday.
Athletic saw off Levante 2-1 in extra time and 3-2 on aggregate to set up a showdown with LaLiga giants Barcelona in the Copa del Rey decider next month.
Supercopa de Espana champions after upstaging Barca in January, Athletic reached last season’s Copa final but, due to the impact of the coronavirus pandemic, they are yet to play it – the match against their rivals Real Sociedad set for April 3.
Athletic are now gearing up for two finals in the space of 14 days next month, with a clash against Barca scheduled for April 17.
“These players have made Athletic Club history and sometimes that only happens once in a lifetime,” Athletic head coach Marcelino said.
“They had to make the most of the moment and they did so.”
