Ferran Jutgla gave Barca the lead in the 50th minute but Exequiel Zeballos levelled mid-way through the second half and the match finished 1-1.
The Argentines then won the inaugural ‘Maradona Cup’ 4-2 in a penalty shootout.
Alves, 38, has rejoined Barcelona where he played between 2008-2016 and won three Champions League titles and La Liga six times; but is ineligible to appear in competitive matches until the transfer window opens early next year.
He was a free agent after leaving Sao Paulo in September following a dispute over unpaid wages.
Rightback Alves was busy and dangerous, and converted his penalty in the shootout.
