In late June 2012, after Nàstic suffered relegation, Juste returned to his first club Barcelona, signing a two-year contract and being assigned to the reserves.[4] However, on 15 July, the former announced that he would return for preseason play.[5]
On 6 August 2012, Gimnàstic and Barça reached an agreement for Juste,[6] and he agreed to a three-year deal with a €12 million buyout clause.[7] He picked up an injury in mid-August,[8] only returning on 8 January 2013;[9] he was again downed by physical problems shortly after, this time in the knee, being sidelined for the rest of the campaign.[10]
Juste damaged his anterior cruciate ligament on 20 August 2013, going on to miss a further several months.[11] He finally made his debut for Barcelona B on 31 May of the following year, playing the last three minutes of a 4–3 home win over AD Alcorcón.[12]
Despite appearing in just one match in two years, Juste was named the B team's captain on 22 August 2014.[13]

Juste moved abroad for the first time on 14 August 2017, signing for Indian Super League franchise FC Goa.[14] He scored his only goal for them on 28 February 2018, opening the 5–1 home defeat of ATK.[15]
