Concerts by Korean Pop band BTS have left part of the pitch at the Stade de France damaged ahead of this weekend's French Top 14 rugby final, a stadium official said on Friday.

An area covering 3 percent of the surface, stretching 3x30m on the halfway line, was affected. Fresh grass cuttings will replace the worn out part of the field a matter of hours before Toulouse play Clermont late on Saturday.

"We held two concerts by the K-Pop group BTS last week, with an absolutely monumental level of production. It was a technical challenge," Alexandra Boutelier, the ground's director said.

But, added Boutelier, the stadium has to have events to generate income.

"We treated the hardness of the ground in a way which kept its technical consistency. We accept full responsibility of this situation, linked to our economic model of the stadium which avoids it from going in the red."

Now i know what @BTS_twt has meant with saying that Stade de France is BIG.

BTS, a seven-piece boy band, held two gigs at the 80,000 capacity arena on June 7-8 after a string of sold-out shows in Los Angeles, Chicago, and London's Wembley Stadium. The band's hit track "Boy With Luv" broke into the Billboard Top 100 songs with over 173 million plays on Spotify. 

The massive follower base of BTS has earned the nickname ARMY. In 2017, BTS broke the Guinness World Record for most retweets and engagements on Twitter. In 2018, the group fell short of the record for most used hashtag amassing 21.9 million uses. 

BTS fans, after investigation we're sorry to announce that the attempt at 'Most used hashtag on @Twitter in 24 hours' was not successful on this occasion. Inc. retweets and quote tweets, the total has been calculated at 21.9 million uses of #iVoteBTSBBMAs https://t.co/w9QEp5SuKk
