Unai Emery has said that attack is the best form of defence for his Sevilla troops in this evening's Europa League visit to Zenit St Petersburg.

The Spaniards take a slender 2-1 first-leg win into the quarter-final second leg but, rather than defend what they have, Emery says that victory is on the agenda in Russia.

"You always want to win, without considering what the score was in the first leg," Emery told reporters. "We could reach the first goal but not the second one.

"We know this is a 180-minute tie and we are ready to play extra time or penalties if we have to. Zenit knows to compete very well, they have a lot of experience and all their players are internationals. They have won a Europa League recently and their coach has experience and has also won a Europa League title himself.

"We are gonna try to compete, assess how the game is going during the 90 minutes and think about our advantage. We will try to win in Zenit's stadium, but we are well aware how difficult that will be."

Sevilla, who won the competition last season, have won it three times in the last nine years.
