Relegation-threatened Livorno have sacked Domenico Di Carlo after just 88 days in charge and re-appointed Davide Nicola.
Virgil van Dijk claims he knows nothing of interest from English clubs and is keen to prove himself in the Champions League with Celtic.
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.
