The Brazilian was released from his contract in June following a difficult spell at the Camp Nou, in which he saw his first-team opportunities limited after his arrival from Palmeiras in January 2020.
“I had no idea about it, and when I received the message I couldn’t believe it,” Matheus told Globoesporte.
“I was at home, I was about to go out with my wife when a message from the club arrived, asking if I had the same email.
“I told them yes and then I received it.
“I didn’t really understand it, it sent it to my agent and to my lawyer.
“They said that it was my dismissal.
“A short while passed before it came out in the press.
“Not a conversation, nothing; they did not even call me to say goodbye.”
Matheus continued to lambast Barcelona for their poor conduct in rescinding his contract.
“It was bad, it was ugly from the club,” he said.
However, he went on to state that it was a continuation of his poor treatment throughout his time at the Camp Nou.
“As a child I always dreamed of playing for Barcelona,” Matheus said.
“When I arrived there, they didn’t treat me like a footballer.
“I told them that they weren’t treating me like a Barcelona player.
“Regardless of whether I earn a lot or little, whether the club have done this or that, I am a Barcelona player.
“Whether I play or not depends on me, on the club and on the other players, but I want them to treat me the same.
“I was a little annoyed.
“Looking at the club from the outside I thought one thing and when I arrived they treated me differently.
“I don’t know if that happens with everyone, but a lot of negative things happened to me.”
