Swansea boss Michael Laudrup believes Michu's Premier League form will make it difficult for Vicente del Bosque to leave him out of Spain's squad for next year's World Cup.
Michu made his international debut for La Roja in last week's 2-1 win over Belarus after being called into the squad following an injury to David Villa.
The 27-year-old, who has scored two league goals this season, was played as a striker by Del Bosque, meaning he will be competing with Roberto Soldado, Villa, Fernando Torres and Alvaro Negredo for a spot on the plane to Brazil.
Laudrup believes a repeat of last season, in which Michu netted 22 goals in all competitions for the Swans, could guarantee the former Rayo Vallecano forward his first World Cup call-up.
"He can make the World Cup squad, he has already proved it," Laudrup said. "Like in every squad there will be players who will be automatic selections and Vicente del Bosque will already know who.
"Players like Sergio Ramos, Andres Iniestia and Xavi, a certain number of players are already there. But for the final three or four places it will depend.
"Is it Roberto Soldado, Alvaro Negredo, Michu, Fernando Torres or David Villa? Will they take two of the five or three of the five? We are talking about a high level there so I think it will depend on what they are doing with their clubs in the last months of the season."
Laudrup expects Michu to use his international experience as added motivation for the remainder of the season.
"It's huge, I would imagine for a player like Michu as the players who get to go into the national team come from the big clubs," he said. "In Spain the big ones are Real Madrid, Barcelona, Atletico Madrid, Valencia, Malaga, Athletic Bilbao, but he was from Rayo and then he joined us.
"Already last season there was talk about playing a friendly or two, but this was a qualifier and he started. It's not just about the World Cup, but playing for the World and European champions.
"In the last four years they have won everything so Michu and Swansea can be very proud as it must be one of the most difficult squads to get into as a player.
"But that's what happens when you are born in a country with so many good players. It gives you the possibility to go to the World Cup, but it means it makes it very difficult to get into the squad."
