Eden Hazard struck the goal that gave LOSC Lille Métrople a 1-0 UEFA Europa League round of 16 first-leg win against Liverpool FC but the 19-year-old warned that the return at Anfield next Thursday will be a stiff task. "We've taken the lead but we know that we'll have to give everything in one week's time in an even tougher game," Hazard said. "Hopefully we can produce the same sort of game Lyon delivered at Real. As for my goal, I'm not supposed to take the free-kicks but I was asked to. I wanted to put it in the box. No one touched it. Good for us. We hope we can keep this advantage."
