Sevilla boss Pablo Machin says they must not underestimate Europa League opponents Lazio.

Sevilla take a 1-0 lead and an away goal into the second leg of their last-32 tie.

Machin said: “We've had worse times. They're part of football, especially when you're a team like us with big objectives.

“It's all in our hands. We have to overturn the situation and tomorrow we'll be back playing in a historic competition.

“We must believe in ourselves and plan the match from the first moment. Tomorrow is a hugely-important match for us. We have to get back to winning.

“We've had chances, but what's missing is consistency. We have to do a bit more than we did before to turn them into goals.

“The team are talented, the players have always shown it, so we must keep doing what we're doing.

“Luis Alberto is an important player for them, but my team worry me more, even if Lazio are a great team. They have nothing to lose.

“(Ciro) Immobile's a player who knows this stadium. We'll keep an eye on him, even if I don't really know his physical level. I hope he doesn't celebrate his birthday against us."
