The Chile forward previously failed to secure first-team football with the Nerazzurri but is craving a second chance, enthusing that "I have always been a supporter"
The 29-year-old was one of the surprises of the 2012-13 campaign as he netted seven goals in 23 Serie A appearances and his good performances have reportedly resulted in interest from Walter Mazzarri's side.
"Playing for Inter has been a dream ever since I was a child. I have always been an Inter supporter," Pinilla told Mega.
"An important Nerazzurri director has told me that it's never too late to re-join Inter. That serves as motivation to me. We will see what happens."
Nevertheless, the attacker admits that a transfer seems unlikely at this point as he is happy with life at his current club.
"I have a two-year contract with Cagliari and we are in talks over an extra year," he stated. "I am feeling very well here in Sardinia and something extraordinary would have to happen if I were to switch clubs."
Pinilla was previously contracted to Inter in 2003-04 but never made it into the Nerazzurri's first team.
