The Argentine praised the Blaugrana captain as a "fabulous person" and wished him good luck as he prepares for the next chapter in his career at the end of the season
The Blaugrana captain announced on Tuesday that he will depart Camp Nou in the summer after spending 15 years in the first team of the Catalan giants.
Messi pledged his support to the 35-year-old centre-back as he believes he will have thought long and hard about the decision to leave and insisted he will be missed by everyone connected to the club.
"It’s a decision that he’s probably thought a lot about, because it’s not easy to make," Messi told television show Mundo Leo.
"If he’s said it, it’s because he’s totally convinced and sure about it. He'll be sorely missed, both inside and outside the dressing room.
Messi went on to wish the Spain international luck on his future endeavours as he plays out the remainder of his final season with Barca.
He continued: "We wish him the very best in whatever he wants to do. Whether he goes to play somewhere else or wants to do something different, I hope it goes really well. He deserves it, he’s a fabulous person."
