Lionel Messi will miss the next three weeks after suffering the recurrence of a groin injury as Atletico Madrid came from behind to hold Barcelona 1-1 at the Camp Nou on Wednesday.
“To lose Lionel Messi means football loses and we lose,” said Barca boss Luis Enrique.
“Now we have to look for other solutions. With Leo we are much stronger, but without him we are still a strong team.”
Messi is set to miss Barca’s next three games against Sporting Gijon and Celta Vigo in La Liga and Borussia Moenchengladbach in the Champions League. He will also miss Argentina’s World Cup qualifiers against Peru and Paraguay.
The five-time World Player of the Year missed Argentina’s last qualifier in Venezuela earlier this month due to a similar injury.
