After losing the 2014 World Cup final to Germany because of a 113th-minute Mario Gotze winner, Messi was glad the same fate did not befall Argentina against France.
Messi released a message on Instagram, saying: "I always dreamed of being a world champion and I didn't want to stop trying, even knowing that maybe I would never give up.
"This cup we got is also from all those who did not make it in the previous World Cups we played, like in 2014 in Brazil, where they all deserved it for how they fought until the same final, worked hard and wanted it as much as I did.
"It's also from Diego who encouraged us from heaven.
"And of all those who spent the time always supporting the national team without looking so much at the result but the desire we always put into it, also when things didn't go as we wanted.
"Many times failure is part of the journey and learning and without the disappointments it is impossible for success to come.
