Barcelona president Rosell delighted with Vilanova return
Vilanova was declared well enough by team doctors to participate in the match.
"He's proving that it's possible to fight against these types of diseases. He's shown great mental and physical strength," Rosell told Barça TV.
"The doctors authorised him to be here tonight and we'll have to see how he feels after the match. He's very eager to lead the team and as long as the doctors allow him, he'll carry the flag of the Club."
Rosell then said that he "has no doubt that the Ballon d'Or [which will be awarded on Monday] will be won by a Barça player. For me, they are the best."
