Former Chelsea forward Salomon Kalou is in trouble after using a hammer and chisel against the Berlin Wall.
The Ivorian, who now plays for Hertha Berlin, was taking part in television filming, when he damaged the wall.
Eastside Gallery own the copyright to the graffiti on the wall, and their chairman Kani Alavi is unhappy with Kalou, who could now face a 10,000 euros fine.
Alavi told the Berliner Kurier newspaper: “I nearly fell off the sofa when I saw the footage. Here we have a well-paid celebrity increasing his market value at the expense of a national monument. Without respect. And with the clear backing of television.
“Just because there is no security patrolling the Gallery, doesn’t mean you can go around doing what you want. If he had done that at the Brandenburg Gate, the player would probably have been arrested.”
