With Messi's contract due to expire in 2018, Suarez feels that nothing will bring him more joy than his teammate renewing his contract with the club.
"My renewal has nothing to do with Neymar or Messi's", Suarez said. "Leo is a legend and he knows what he has to do and decide", added Suarez.
"He's a person I admire a lot, for him to come and tell me those things, it was something that really helped me in that moment", he said. "We are friends and we have a great relationship, but he is an adult and he has to take that decision".
"It's a very important day for me and my family".
"I would like to have a good year, finish it well as a collective, fighting for everything with the club and qualifying directly for the World Cup with Uruguay, something we've not done for a while". "Now I want to keep enjoying myself and winning titles". I never put any obstacles in the way of a renewal.
"Any player would want to end their career at a club where they feel comfortable". "We will have to see, but I will never lose either my ambition or my enthusiasm".
Suarez struggled to integrate into the Barcelona team at first, having joined the team after a troubled time at Liverpool and the 2014 FIFA World Cup, where he was suspended for biting Italy defender Giorgio Chiellini on his right shoulder.
"Everyone has their own criteria. He's the best", Suarez said.
