Midtjylland chairman Rasmus Ankersen has defended his club's decision to charge Manchester United supporters £71 for tomorrow night's Europa League tie in Denmark.
“It’s a big game for the region, we could have taken in to another stadium and sold 50,000 or 60,000 tickets, but wanted to dedicate this game to the fans who come every week," Ankerson told BBC Radio 5 live.
"We are charging the same amount for Danish fans as Manchester United fans. Our fans have not complained about it. I understand the frustrations of the United fans but we have to try to make everyone happy.
“It’s a lot of money but people here think this is a once in a lifetime experience.”

If European football is your thing - and since you're here reading this, I have a feeling it might be, check out the European Football Show on BBC Radio 5 live tonight from 21:00 to 22:30 GMT.
Mina Rzouki, Julien Lauren and Steve Crossman will be discussing Serge Aurier's suspension by PSG, Liverpool new boy Joel Matip and Europa League side Midtjylland. There will also be an interview with Napoli keeper Pepe Reina on his side's title bid.
Barcelona are dominating. To be honest you didn't need to read the stats to know that would be the case.
Under-strength Sporting Gijon are lucky to still be in this really although they've defended well.
Lionel Messi has scored his 300th - and 301st La Liga goal - as Barcelona threaten to go six points clear at the top.
The referee lost his footing and fell over - a moment that's funny no matter what league it happens in.
Barca are starting to get a bit frustrated as Sporting's defence are standing strong. Arda Turan concedes a free-kick for knocking over Alex Menendez while trying to get the ball. The visitors should be further ahead.
Neymar sends his defender one way and then the other with some great footwork but then he flashes his shot against goal and wide of the far post from an angle.
Sporting are lucky to only be one goal down, they're being totally dominated now.
Lionel Messi now has 301 La Liga goals. Telmo Zarra with 251 is second on the all-time scoring list.
Cristiano Ronaldo is third with 246.

John McEnerney: Sporting play some nice stuff which is surprising considering Albeardo was a hoofer/hatchet man in his playing days.
It's almost a Lionel Messi hat-trick as he gets the ball on the edge of the area and forces a save from Ivan Cuellar when you'd expect him to score.
The ball breaks to Neymar... and his curler hits the post.
Sporting Gijon are on the ropes now.
Lionel Messi
Lionel Messi plays the ball over the defence to Luis Suarez, who holds the ball up, turns and plays it back to Messi, who smashes home from about 10 yards out.
He starts the road to 400 La Liga goals...
I really wasn't expecting that. Remember Sporting have put out a weakened team, with the weekend's match against Real Betis in mind.
Neymar has a shot for Barcelona but it's straight at the keeper.
Carlos Castro
Scenes.
Sporting Gijon are level almost immediately. They play a few passes around the box to work it out to Alex Menendez out left and he fires in a low ball across the box which Carlos Castro slides in at the far post.
Lionel Messi
Lionel Messi turned down the chance to score his 300th La Liga goal when he set up Luis Suarez with his penalty the other day.
Well today, he's reached the landmark. The Argentine gets the ball outside the box and just lamps it into the bottom corner. Great finish by a legend of the game.
It's some pretty desperate defending by Sporting Gijon at the moment, players throwing themselves at the ball to deny Lionel Messi and Arda Turan in a Barca attack.
They'll be happy to make it to quarter-way through the game level.
Neymar slips the ball through to Luis Suarez, who darts in behind the Sporting defence but his shot from eight yards out is well saved by Ivan Cuellar.
Sporting defender Jorge Mere is back on with a head bandage.
