The 26-year-old has recently been strongly linked with a move to Premier League side Chelsea.
Mascherano left Liverpool for Barcelona in a £18million deal last August.
He told The People: “I have heard the rumours, but I am calm about my situation.
“I have spoken to nobody because I see my present and my future at Barca, and I don’t want to leave this summer.
“It is a privilege to play some minutes in this super-squad and my mission now is to be patient, to learn and to perform at my best when opportunities come.
