The former Ajax midfielder joined the club last summer and it looks as though he will only have been able to enjoy playing alongside the six-time Ballon d’Or winner for single season.
The 23-year-old looks certain to play a starring role under Ronald Koeman having worked with the former Everton boss as international level, but the same cannot be said for either Messi or Luis Suarez.
De Jong has now opened up on his thoughts during what is a very difficult time for the Catalan giants, and he has admitted that the exit of their captain would be a huge blow.
The midfielder told NOS after training with Netherlands: "It is chaos, there is a lot going on.
"I did not talk to him about this myself. Not even the club. So I honestly don't know about it."
Before adding: ”But if Messi really leaves, it will be a huge blow to the team and the club.
“But when I come back after these international matches, I will see what happened at the club."
In a further interview, De Jong revealed that Messi is still in the group chat with the players, but that is not surprising when you consider that his issues at the club have been with the hierarchy.
De Jong added to Fox Sports: "I hope that Messi is still there when I get back, but that is not something that is up to me.
“He's still in the group chat.
"I'm not anyone to talk about it with him, I'm sure he has many people around him doing that these days."

Manchester City remain the favourites to sign Messi as he attempts to leave his boyhood club for free, despite Pep Guardiola stating earlier this year that he didn’t want the Argentina talisman to leave Barcelona.
"He is a player from Barcelona and he will stay there, that's my wish for him to stay there," he said.
"I'm not going to talk about players playing for other clubs. I think he will finish his career there, that's my wish."
