Juan Sebastian Veron made a sensational return to professional football as Estudiantes lost to Barcelona in the Copa Libertadores, while Gremio preserved their 100 per cent record.
Club president and 42-year-old midfielder Veron started in 10-man Estudiantes' 2-0 loss to Group 1 leaders Barcelona on Tuesday.
Veron was due to make his return on matchday one against Botafogo last month, having made himself available after fans reached his target of box sales in Estudiantes' new stadium.
