The 21-year-old midfielder insists that his team-mate will strive to take part in the tournament, while saying that Tito Vilanova will introduce new things in the Barcelona teamBarcelona attacker Thiago Alcantara does not rule out Carles Puyol's presence at Euro 2012 with the Spain national team.
The Camp Nou outfit announced earlier on Tuesday that the defender is facing six weeks on the sidelines as he will have to go under the knife after sustaining a knee injury at the weekend.
Such a scenario practically rules Puyol out of this summer's showpiece event, but Thiago declared that his countryman will work hard to be available for the tournament.
"It is a big loss for the Copa del Rey final and Euro 2012, I do not know if he will be available," he told a press conference.
"No one wants to miss a Euro, much less someone like captain Puyol, who has tremendous determination.
"He will do his utmost to be at the tournament."
The 21-year-old also commented on the managerial chances at Barcelona, saying that there will be a seamless transition from Pep Guardiola to Tito Vilanova.
"We will not have any problem to identify Tito as our coach," Thiago said. "We respect Guardiola's decision, but his exit is painful and hard because he means a lot to the club.
"The good thing is that Tito is taking over. Although Pep was most of the time in charge of psychological matters, it was Tito who took care of tactics.
"I am sure that we will see new things with him next season."
