Tottenham midfielder Erik Lamela says they must not underestimate Fiorentina in tonight's Europa League tie.

The scoreline is locked at 1-1.

"We've got a tough match ahead of us tomorrow. We must play our own game," Lamela said.

"It's very important and we have to win.

"I think of Fiorentina as a strong team that will try and impose their typical style.

"It's going to be an open game as both teams want to dominate. I hope it's going to be a fun match."
