Palace face Shakhtar in Poland for tonight's first-leg.
“I'm really happy,” Lacroix said. “Of course, it's the first time for Palace, but we hope that we can go to the next step – so it starts Thursday, with the fans. A lot of people are coming, so we need them there.
“We played already in Poland last time (against Dynamo Kyiv in October). It's difficult (with the atmosphere). But we will go there to win. We are football players, and we want to win and reach the final.
“It's going to be a tough game, but we're going over there to win.
“We want to win another trophy. I think we just say: everything is possible. We showed it last year and I think people, when they come to support us, they see that we can do something this year.
“We want to give them this trophy, but you have to be respectful and start with Shakhtar on Thursday.”
