Yeah. He is a controversial player just like other legends such as Maradona etc, but the dude can play which is why he is a suitable candidate indeed. However, he needs to minimise getting into more controversies though.
He bite other opponent players three times, one in Ajax Amsterdam, one in Liverpool and one in World Cup 2014 in the match between Uruguay and Italy. He changed himself a lot after moving from Liverpool to Barcelona and my memory is Luiz Suarez played without drama in Barcelona. He got older, more matured and also learned from his past lessons to avoid some emotional instinct mistakes in later of his career.
If he doesn't, that would harm the reputation of Duelbits to a certain extent basically.
I believe at this age, Luiz Suarez knows how to do things rights and will try to use his reputation to get more money before his name will no longer be attractive globally. I read news that he is a man of family and with his love for his family members, he will be more careful with his reactions.
