Chelsea striker Fernando Torres is understood to be set for a return to Atletico Madrid, according to Sky sources.
Mark Hughes insists Stoke will not be looking to make any major additions in the January transfer window.
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.
