The club have confirmed that almost all of their revenue streams have been embargoed by the Spanish tax authorities to reclaim 34million euros owed to them by the club.
Despite the off-field issues, Oltra has said he has not detected any change of attitude amongst the squad and that the news should not affect them ahead of their trip to Zaragoza this weekend.
He told Marca: "I haven't detected anything. Probably, they are things that we cannot control. I don't have all the information and I am not the right person to transmit that information.
"Yesterday [Thursday] we were away from these statements and I am in charge to ensure that this has no influence. I could have seen a group that wasn't concentrated, nervous, worried, but in reality today I haven't seen anything and I don't think we have to be alarmed."
Oltra's team selection will however be affected by injuries to Carlos Marchena and Ayoze which should mean returns to the side for Evaldo and Aythami, whilst Abel Aguilar remains on the sidelines and Nelson Oliveira is also expected to miss the next couple of weeks with a muscle injury.
Zaragoza by contrast have had a very quiet week and despite losing 4-0 to Real Madrid last weekend, Manolo Jimenez is expected to stick with the 11 that started at the Bernabeu.
Maurizio Lanzaro and Ivan Obradovic remain out injured, but Adam Pinter is now fit again and should take his place on the bench.
