Luis Suarez paid tribute to Lucas Leiva who announced his retirement.
Gremio lost the game to RSYpiranga-RS 2-1. Suarez opened the scoring after just 12 minutes.
Suarez unveiled a t-shirt underneath his kit with a message written “Lucas our heart is with you”.
The Brazilian retired after a heart issue was discovered in tests in December.
The 36-year-old played at the heart of Liverpool’s midfield for ten years before leaving Anfield to join Lazio in 2017.
