On Tuesday, continuing troubles forced the stadium manager to step down - less than four months before the £408 million stadium is due to stage the opening match of the European Championships between Poland and Greece.
There is also continuing criticism of Poland's newly-appointed 35-year-old Sports Minister Joanna Mucha, who is constantly at loggerheads with hardliners from Poland's Football Association (PZPN).
Asked what would happen if he could not lead the team out in the capital, Smuda told reporters: "We will play in Wroclaw, but I would prefer to play in Warsaw, finally."
While the political infighting and problems with the stadium are going on, Smuda's main concern is to produce a team which can bring a smile to the faces of fans who have not had a lot to celebrate since Poland reached the World Cup semi-finals in 1982.
"This is our last test against such a strong opponent ahead of the Euros," Smuda said, adding that his squad for the Portugal game would be more or less the one he will employ in June.
"One could say its 90, 95 or 99.9 percent.
"It's hard to say exactly now as every week injuries happen and somebody falls out of the game. But over the last two years I have achieved my goal, I know who to focus on, my first eleven is in place."
Borussia Dortmund's Polish trio of Lukasz Piszczek, Jakub Blaszczykowski and Robert Lewandowski are all included while both of Arsenal's goalkeepers Wojciech Szczesny and Lukasz Fabianski are named in a 22-man squad.
Asked to comment on Mucha's performance nearly 100 days after she was sworn in, Smuda said: "Well, Minister Mucha is a pretty woman, that's for sure, and will do anything to work things out.
"I'm sure she will become a very good sports minister."
