The Belgian side will welcome Paulo Sousa's team to the Cristal Arena for the first of their Group G fixtures on Thursday evening.
Tougher matches lie ahead for Genk as Sporting Lisbon and Basle make up the rest of their group, but Been has already seen Videoton overcome another Belgian side, Gent, in qualifying.
"Sporting Lisbon is the toughest opponent based on status and results of the past," Been told his club's official website, www.krcgenk.be.
"Basle is also a very tough opponent and Videoton should definitely not be underestimated.
"Teams at this level have more than earned their place and there are no ugly ducklings once you are in the group stage.
"We have, despite the young age of our team, a mature and experienced group even at this level.
"I am firmly convinced that we have the qualities to get results in the pools, starting against stiff opponents Videoton."
It will be the first time the teams have met, although Videoton's Balasz Toth is well placed to give his team-mates some advice.
The midfielder played for Genk between 2007 and 2011, scoring eight goals in 69 league games.
"They are a very well organised side who play aggressive football and this is their main strength," Toth told the club's official website, www.vidi.hu.
"I believe that Genk will be similar with our other Europa league opponent Gent, but their style of football is totally different.
"Genk are physically stronger, and as I have already mentioned, use their power and strength."
