Valencia manager Marcelino Garcia was asked last week whether he would rather finish in the top four of La Liga or win the Copa Del Rey, and the coach begrudgingly admitted that a return to the Champions League would probably be of greater importance to the club.
Nevertheless, Los Che will look to enjoy a successful cup run as well this season and they are well placed to make it through to the next round of the competition after a 2-0 first leg win at Real Zaragoza.
Given the score from the first game last month, both teams are likely to rest players for Thursday's match at Mestalla and Valencia will likely give some youth players a chance.
Zaragoza, meanwhile, are likely to prioritize their Segunda Division clash against Sporting Gijon at the weekend.
Valencia's nine match winning run in all competitions came to an end on Sunday with a 1-1 La Liga draw against Barcelona, although Los Che will still want to maintain their unbeaten start to the season on Thursday evening.
Paddy Power price a home win at 1/4 (1.25) while Zaragoza are available at 9/1 (10.00) - despite having recorded just one away win in their last six games on the road in Spain's second division - with the draw offered at 9/2 (5.50).
Even if the visitors were in great form, it would be quite an ask for them to win at Mestalla, but the fact is Zaragoza have been really struggling of late with just one win in their last eight games.
Therefore, the price of 7/4 (2.75) for a home win by a 1-0, 2-0 or 3-0 scoreline appeals, with this bet paying out in three of Valencia's last four victories - including in the first leg in Zaragoza - and is even more tempting with the visitors unlikely to be particularly motivated to produce a comeback given where their priorities lie.
