Athletic Bilbao coach Ernesto Valverde will have seven youth teamers added to his senior squad for preseason.
Two of them are goalkeepers. Alex Padilla, 19, returns after spending last summer with the Lions and is joined by 19-year-old keeper Oier Gastesi, who played for Basconia last season and will be promoted to the B team for the upcoming campaign.
Full-backs Hugo Rincn, 20, and Miguel Barandalla, 19, as well as centre-back Unai Egiluz, 21, have also been called up. Egiluz has made 27 appearances for the reserve team, right-back Rincn has featured 29 times and left-back Barandalla, who has been playing with Basconia, got his first minutes as a Cub last season.
The other two are midfielders. Unai Gmez, 20, and Junior Bita, 18, who both trained frequently with the senior side in the second half of last season, also make the squad. Gmez was a regular with the reserves, making 34 appearances and scoring twice until Valverde brought him into the first-team fold. Bita, who played around ten games for Bilbao Athletic, was in the senior matchday squad for the last three games.
