Firmino will leave on a free status from Liverpool, this will be a bone of contention for several Premier League teams. Firmino's quality is recognized, and I think he is still very good to play in competitive leagues such as the Premier League, La Liga, Serie A and others. Barcelona also need a striker, but Firmino's future has yet to be decided where he will go.
Roberto Firmino have announced will leave Liverpool at the end this season and become free agent player, seems can't get regular position after arriving Darwin Nunez and spent more minutes in the bench make him not happy and not reach agreement extended contract. No doubt with Firmino quality and his achievement success give primer league and champion league tittle for Liverpool.
I think Serie A, La Liga or keep stay in Primer League still the best option for him trough 31 years old and potential for several years later on the top performance. I think Firmino not priority with Barcelona because difficult get regular position there and seems possible removed Lewandowski from regular position.
