Here’s everything you need to know about Rosenborg
The first leg of this tie takes place at the Lerkendal Stadion tonight with a 6pm kick off.
The second leg is set for Thursday August 17th at Tynecastle.
It has been reported just 6,000 tickets have been sold for the first leg, meaning the stadium could be half full come kick off.
The venue holds a capacity crowd of 21,000, with Hearts allocated just 800 away tickets.
These sides have never met in Europe before but Rosenborg have faced Celtic on ten occasions, winning just once and losing seven. They also lost 2-1 to St Johnstone in a Europa League qualifier in 2013.
Rosenborg are currently midway through their domestic season, but they won just three of their first 14 games.
Their form has picked up since then, with four straight wins, as well as a 5-4 aggregate victory over Northern Irish side Crusaders to books a meeting with Hearts in this Third round qualifier.
That game went to extra time with a late Leo Cornic goal sealing the win after the Irish side had gone down to ten men.
Rosenborg currently sit eighth in Norway’s Eliteserien after 18 games, winning five of their last six games in all competitions.
Danish striker Carlo Holse will be a player for Hearts to be wary of, with the forward scoring three goals this season including in the away leg against Crusaders.
Here’s everything you need to know about Hearts
Hearts are desperate to return to the group stage of the Europa Conference League and they will have the chance to do so when they face Rosenborg in the Europa Conference League Third round qualifier.
Hearts secured a Europa Conference League Third round qualifier spot after finishing fourth last term under Steven Naismith, with Frankie McAvoy taking the reigns this term.
Hearts kicked off their Scottish Premiership campaign at the weekend with a 2-0 win over St Johnstone, with goals from Yutaro Oda and Lawrence Shankland.
Lawrence Shankland fired in 28 goals for Hearts last term, including three goals in Europe for the Jambos.
Another player who could play a vital role, most likely in the second leg, is new on loan striker Kenneth Vargas, who signed from Costa Rican club CS Herediano.
Alex Lowry could also play his part in the game after signing on loan from Premiership side Rangers.
The winner of this two legged tie will take on Hadjuk Split or PAOK in the UEFA Europa Conference Play-off round for a spot in the group stages.
