Sporting Lisbon have condemned reported acts of violence towards some of their players by a group of fans at the club's training ground on Tuesday.
The Portuguese Primeira Liga club finished the season third after a 2-1 defeat at Maritimo on Sunday and just missed out on a place in next season's Champions League.
The players were preparing for Sunday's Portuguese Cup final, where they take on Alves, when the alleged attacks took place.
