"Whatever happens in the final, Messi and Neymar have been the two big stars of this World Cup," Bartomeu told the club's official website.
"Until the injury, [Neymar] was having an incredible tournament. Despite his youth, his progress as a footballer and his leadership made a mark on the Brazil team.
"We have been close to him since the injury, the medical services have been in contact with him and his family. It was a nasty shock for all football fans, especially those of Brazil and Barca. I hope he gets fit again soon and I wish him all the best. He is very young and will have plenty more chances to win things for his country."
Neymar and Messi will be joined by Luis Suarez in the Barcelona attack next season.
