Levante put in an uncharacteristically ragged performance to lose 3-0 to Rayo Vallecano last time out and their chances of getting back on track this weekend will be hampered by the absence of Obafemi Martins through suspension.
Ángel is therefore likely to be handed a rare start up front and there could be even more problems for Juan Ignacio Martinez should Jose Barkero fail to shake off an ankle injury.
Pedro Rios is the most likely candidate to replace the veteran midfielder should he not be fit, but Christian Lell returns from suspension and is expected to start at right-back.
Athletic's positive momentum after two consecutive victories was stopped in its tracks by another disappointing home defeat to Real Zaragoza just before the winter break, but Marcelo Bielsa does have a number of key players back for the trip to Valencia.
Fernando Amorebieta and Carlos Gurpegi are fit again, whilst Markel Susaeta will return after being suspended last time out.
Jon Aurtenetxe is a major doubt so Oscar de Marcos is expected to deputise at left-back.
It is very rare for this Levante side to put in two bad performances back-to-back, but without their favourite outlet in Martins they may struggle to bounce back with all three points this weekend.
Despite Fernando Llorente entering into talks with Juventus, the one thing Athletic don't lack is a goal threat as Aritz Aduriz leads the likes of Roberto Soldado and Alvaro Negredo as the highest scoring Spaniard in the league and the return of Susaeta should also greatly improve the service towards the former Valencia man.
The Basques still lack the spark that saw them shine - particularly at this stage of the season - last year and they won't be too disappointed with a point away at a difficult venue.
