Liverpool have been warned to expect a shock from Debrecen on Tuesday night.
The Reds travel to Hungary as hot favourites to beat a team without a point from their first four matches in Champions League Group E.
Rafa Benitez's side only managed a 1-0 win at Anfield and need a victory to have any chance of staying in the competition.
But Hearts manager Csaba Laszlo, who knows Debrecen from his time as coach at Ferencvaros and assisting Lothar Matthaus with the Hungary national side, told The Sun: 'It's a big adventure for the smaller teams, I know that very well. And when you are something of an unknown, that's when you have your biggest chance. That's when you can cause a surprise.
'I saw the first game at Liverpool and, OK, they had a lot more of the ball, but even then they weren't too dangerous and only won 1-0. And Debrecen, as we have seen especially in the last couple of games, can score goals.
'I tell you now, it won't be easy for Liverpool to win.'

TELL US WHAT YOU THINK Benitez has guided his side to just one win in their last 10 games and a Fiorentina victory over Lyon will leave the Spaniard facing a Europa League campaign.
Laszlo added: 'All of the players are basically trying to sell themselves. It will be televised all over Europe, other managers and agents will be watching, and it's a great chance for them.
'They're not just playing for their pride, they're playing for a place in history - for the manager, the players, the whole club.
'It's their last home game, their chance to show the whole of Europe what they can do, and all the pressure will be on Liverpool.'
