Mauricio Pochettino expects to be at Southampton next season and is looking forward to working with chairman Ralph Krueger.
Loan pair Sam Hutchinson and Leon Best have extended their deals at Sheffield Wednesday.
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.
