The Shrewsbury manager, Steve Cotterill, reacted with anger after his goalkeeper Marko Marosi claimed to have been racially abused by a supporter during their 2-0 League One defeat at Charlton. The Slovakian reacted to a comment from the crowd before his side conceded a second goal from a free-kick. A hold-up of more than five minutes involved the referee, Sam Purkiss, talking to ground security at the Valley. “Our goalkeeper had something shouted at him,” said Cotterill. “I’m not prepared to repeat it, if I did it would be very offensive. It’s certainly not timely in this moment, with what’s going on in the world. And also, to get his nationality right would be handy. “He’s OK, it’s not a nice thing that happened today, I don’t know if it’s the first time it’s happened to him in his career. I don’t think Marko will press charges. It’s best to let it go, otherwise he’ll be targeted – I think it was more about getting the person out of the ground for what he said to him.” Charlton confirmed an individual had been arrested and was in custody. They said they were supporting the police with their investigations, adding: “We have a long history of promoting equality and tackling discrimination. Discrimination has no place at this club or in football.” Shrewsbury said they were “disgusted” by the “alleged vile racist abuse”, adding: “We hope the individual learns that this abhorrent verbal abuse will not be tolerated anywhere in football or in any walk of life. “Shrewsbury Town stands together against discrimination and we stand with Marko. We will provide Marko with any support he needs and we will do everything within our power to ensure this incident is dealt with appropriately.” The incident overshadowed a win for the south London side, secured with two second-half goals. Charlton’s manager, Johnnie Jackson, said: “It’s a delicate matter. The club will now look into it.”
