The Giallorossi's 1-0 win over Fiorentina ensured they cannot be caught by third-placed Napoli in the race to qualify for Europe's top competition
Radja Nainggolan scored the only goal of the game at Stadio Artemio Franchi on Saturday as Roma beat Fiorentina to open up an unassailable advantage over third-placed Napoli in the Serie A table.
Juventus look set to retain their title with four games remaining, but Totti was nonetheless delighted with Roma's achievement of sealing a spot in Europe's premier club competition.
He told the club's official website: "Fiorentina play good football and are very strong and to beat them at home shows how we continue to improve, step by step, and proves our winning mentality.
"We are very happy to have gotten through to the group stages of the Champions League next year, because that was our goal going into the season and we have done it before the end of April which is a source of both pride and satisfaction."
Roma trail Juve by eight points and have a 14-point lead over Napoli.
