"We were lucky because we left it quite late," the Argentine told BBC Sport. "I just want to congratulate the players because they did fantastic.
"It's been an amazing season. We still have three more points to go for to even surpass the record we've achieved so far.
"It's been a long, hard season but I just want to congratulate the players, all the medical staff and also the fans because they've been amazing throughout the season."
