Sevilla coach Unai Emery insists the task facing his side in their bid to reach the Europa League final for the third successive season is "big."
After last week's 2-2 semi-final first leg draw with Shakhtar Donetsk in Ukraine, Emery is aware of the challenge they face against Mircea Lucescu's crack outfit.
"To get to a final you have to take your chances. We need to give our opponents as few of them as possible. Both sides want to get to the final and it will be a very even game," he said.
"We're expecting the best Shakhtar there is - they won the tournament in 2009 and they're used to winning their league. Their coach is much more experienced than I am.
"It is a big ask - they'll be 90 tough minutes and we need to be ready for it."
The Spanish outfit have won the last two Europa League trophies, beating Benfica back in 2014, while dispensing with another Ukrainian outfit Dnipro Dnipropetrovsk in last year's final.
Shakhtar Donetsk, meanwhile, announced themselves as a force in European football by winning the UEFA Cup - before it was rebranded as the Europa League - in 2009.
Beating domestic rivals Dynamo Kiev in the semi-finals, Shakhtar topped that by overcoming a much-fancied Werder Bremen side 2-1 in the Istanbul final.
