West Ham will seek assurances about security arrangements at the Europa Conference League final after the hooligan disgrace of Alkmaar.
UEFA will launch an investigation into the violence that marred the Hammers' last-gasp semi-final winner in Holland, which prompted hooded, black-shirted ultras to storm the enclosure reserved for players' families – including manager David Moyes' 87-year-old father.
Angry players including Michael Antonio, Said Benrahma, Aaron Cresswell, Flynn Downes and Lucas Paqueta leapt over the perimeter barrier to protect friends and relatives. Now concern is already mounting about the final against Fiorentina in Prague's 20,000-capacity Fortuna Arena on June 7.
