Calderon told Stats Perform News: “It would be really hurtful for the image, the quality, the show [in LaLiga if Messi went].
“We have been really lucky having Cristiano Ronaldo and Messi playing in our league for the past 10 years, the best two players in the world by far.
“They won’t be here anymore, neither of them will be with us. It is really hurtful for our league and for the fans.”
Calderon revealed his surprise at Messi’s request, although he acknowledged the scale of Barca’s recent failings made the move understandable.
“Recent events have surely made Messi upset,” he said. “It is a weird time because he is a winner, as Barcelona used to be.
“The defeat against Bayern has hurt him a lot, for sure. That makes Messi reconsider his future, especially because there will be a World Cup in two years. I am sure he is aiming to be there and to win the cup.
“So, he has probably thought the future of Barcelona is not the best for his goals and he takes that decision.
“It has been a bit shocking for me because I thought he had already decided to finish his career at Barcelona, but it looks like these latest actions have influenced him to leave the club.”
