Group E Kick-off 19-45 (BST)
Fiorentina coach Cesare Prandelli has admitted he is concerned about the counterattacking threat of their Hungarian opponents Debrecen.
While Fiorentina could go six points clear of third-placed Liverpool with victory, Debrecen are yet to get off the mark, having lost 4-3 at home to Fiorentina a fortnight ago.
“I’m not very relaxed about the match, because most people will think it’s going to be easy, but nothing is easy in football,” said Prandelli. “We’ll have to play well and get three points which are crucial for our Champions League campaign.
“I’m expecting Debrecen to play attacking football, so we’ll have to be good in defence, and also keep the right balance. Debrecen are good with the ball and they’re particularly dangerous on the break down the middle. They’re a side who can cause you problems, but we’re not afraid.
“We’ve overcome many problems over the past few years and this is the most important moment of them all, because we have a chance to keep the dream alive for our fans. I hope that at least one of our two injured players will be fit; most probably it won’t be [Stevan] Jovetic, but [Adrian] Mutu might make it.”
With the visitors seeking the win they need to keep their hopes alive, coach Andras Herczeg promised to put on a show for their supporters.
“We know that we will play a big team and it’s important to go hard at this match,” he said. “We examined the last game and have found our mistakes. Fiorentina are favourites to win, but it’s important for us to play a good match and make a good impression in Italy.
“We had a good week training and we will face Fiorentina with heads up, trying to get a good result. We will play mainly for our supporters. In our group there are big teams that think they are playing easy matches against Debrecen, but we will try to make them hard.
“We are relaxed because we are a little team facing three great teams in Fiorentina, Liverpool and Lyon, but we would like to leave a positive impression with our supporters.”
