Borussia Dortmund coach Marco Rose said more should be done to prevent the club's supporters from invading the pitch during home matches.

Earlier this month, the club's striker Erling Haaland handed his jersey to a pitch-invading fan.

"This shouldn't be allowed to explode exponentially and that three or four people get onto the pitch every game," said Rose.

This comes after a Dortmund fan invaded the pitch following the final whistle of Tuesday's 2-0 German Cup win over Ingolstadt and managed to get the playing shirt of Brazil midfielder Reinier.

"We have to find a solution so that this doesn't happen every weekend," said Rose who helped escort the fan off the pitch on Tuesday.

"I can understand the fans trying to get a shirt, but basically everyone knows that we should try to stop this."

With 80,000 fans able to fit into the club's stadium, Signal Iduna Park, at full capacity, Rose warned that "if 80,000 do the same thing, we will have our work cut out."

The coach explained that he intervened on Tuesday to prevent stewards from roughly handling the pitch invader.

"Nobody should get injured," he said, but admitted that the stewards "were just trying to do their job."
