The Spaniards head into the final Europa League Group H clash in Germany saddened by Sevilla president Jose Maria Del Nido's decision to step down from his post after 11 years in charge.
The club's major shareholder, Del Nido, who has presided over Sevilla's most successful time
during which they won the UEFA Cup in 2006 and 2007, recently lost an appeal against a seven-year prison sentence for misappropriation of public funds.
"We want to dedicate every victory to Del Nido," Cala said. "He has been like a father to us, a great president and now he will be our biggest fan.
"Sevilla has gone through worst cases than this one and I don't believe this will affect the team.
"This club is a big institution and it has transmitted us confidence and calmness.
"Now we are going to Germany to win."
A draw at the Freiburg Stadion would allow Unai Emery's men to secure top spot and progress unbeaten to the round of 32.
Despite a 1-1 home draw against Estoril a fortnight ago, the Spaniards lead the pool with nine points.
Freiburg lie three points behind them and are level on six points with Slovan Liberec, who face bottom-side Estoril in the other pool game.
The Germans, who lost 2-0 in Seville in round two, have to equal or better Slovan's result in order to advance.
However, Freiburg are winless in four European home games and go into the match on the back of Sunday's 3-0 loss against Wolfsburg, their third straight league loss.
The result dropped Christian Streich's side to 16th place in the Bundesliga.
Sevilla, meanwhile, beat Granada 2-1 at the weekend to secure their third straight victory in La Liga and climb to eighth position.
