Liverpool closing on Sevilla left-back Alberto Moreno and Atletico Madrid's Javi Manquillo, Sky sources understand.
The agent of Porto's Juan Quintero has played down reports linking the Colombia star with an imminent move to Arsenal.
Pinto, the long-term back-up to Victor Valdes, has agreed a new deal until June 30 2014 and will put pen to paper "over the next few weeks", the club confirmed on official website fcbarcelona.com.
The 37-year-old joined Barca on loan from Celta Vigo in 2008 before agreeing a permanent deal the following season.
He has made 54 first-team appearances, the majority of those coming in the Copa del Rey which he has won twice with Barca, in 2009 and earlier this year.
