"It's difficult to say [how big a threat Debreceni are] but they have won eight games in a row, they're doing well, have some confidence and play good counter attack. They have some pace and players with ability," said the boss.
"Everyone is saying we are at Anfield, we are favourites and have to win, but you never know in these games.
"I read some interviews with their players and they are really, really excited about coming here and want to play well.
"So, we are favourites but we have to prove this on the pitch.
"Clearly we have confidence we can do it. Our experience is that if you don't start well you have to work harder afterwards. So we want to do our job from the first game."
