For staffing, note that Carlos Marchena is no longer the assistant coach. Chema Sanz is the new assistant coach.
For Under-19 i would recommend adding David Otorbi, who is considered to be one of the brightest youth prospects in the club, and has been chased by big teams like FC Barcelona https://www.eldesmarque.com/futbol/valencia-cf/20231019/david-otorbi-convencido-con-alcanzar-el-primer-equipo-del-valencia-cf-tarde-o-temprano-llegare_300127027.html
