After the no-promotion there will be an expected "revolution" (well, more like a further rejuvenation) in Barca B next season according to Albert Roge.
GK:
Situation is pretty clear here. Carevic and Arnau Tenas were both renewed a few weeks ago and will compete for a starting GK spot.
Inaki Pena will be promoted to the first team and depending on what happens with Neto either stay as MATS's backup or be loaned. Juvenil A GK Ramon Villa will be called up if/when needed.
Defense:
Dani Morer will stay as the only defensive starter from the playoffs games. Araujo will be promoted to the first team while Akieme and Cuenca will be sold. Mingueza should stay and be one of the leaders of a newly formated defense. Arnau Comas is returning after a successfull loan at Olot while Juvenil A CBs Ramos Mingo, Igor Gomes and Josep Jaume will be promoted alongside fullbacks Sergi Rosanas (he's out for 5 months though) and Mika Marmol. Depending on the signings some of them could leave on loan.
Midfield:
Jandro and Ilaix will be key players of the new midfield. Monchu will leave though the club don't want to fully give up on him yet (so probably be sold with a buy-back). The same with Collado who is currently injured. Alvaro Sanz and Fran Gonzalez will be promoted while Lucas de Vega will return after a loan at Cartagena who he helped to get promoted to Segunda. Reis's future is uncertain and Pimienta would like to keep Ferran Sarsanedas for his experience and leadership for a young team despite his injury problems.
Forwards:
The main goal is to find a good goal scorer. Rey Manaj has disappointed and Matheus also didn't show much. Konrad who has already established himself as a Juvenil A player will be officially promoted, the same with Nils Mortimer and Peque while Jaume Jardi will rotate between Barca B and Juvenil A. Hiroki Abe and Labinot Kabashi should have an important role when they recover from injuries. Also, Gustavo Maia's signing will be officially confirmed soon.
So something like this.
GK: Carevic, Tenas
RB: Morer, Rosanas (?)/???
CB: Mingueza, Comas, Ramos Mingo, Igor, ???
LB: Marmol/????
DM: Orellana, A. Sanz
CM: Ilaix, de Vega, Fran, Labinot, Reis?, Sarsanedas?, ????
LW: Konrad, Nils
CF: Manaj?/????, Peque
RW: Maia, Hiroki, Matheus?
So If we'll look for more signings I think it should be for a LB and/or RB, a striker and maybe a more experienced midfielder.
