At least 10 premier league football trainers, board members and players have received serious threats in the past four years, broadcaster Nos says on Tuesday.

They have been stalked by supporters at home, received threatening phone calls and pelted with eggs, the broadcaster says.

Nos polled the 18 Eredivise clubs in the wake of the news that several Feyenoord supporters had been arrested for making death threats against Marko Vejinovic. Last week, Vejinovic’s team mate Michiel Kramer was confronted by a group of supporters in his garden who told him to ‘get lost’.

Five clubs

The threats involve five clubs – Ajax, Cambuur, De Graafschap, Heerenveen and Roda JC. In some cases, the people under threat were given extra security for a time.

Five Cambur supporters were jailed for storming the club’s stadium in 2014 while looking for head coach Dwight Lodeweges after he announced he was leaving for arch rival Heerenveen.
