Samu Costa and Molumby, players from Mallorca and West Bromwich Albion, respectively, got into a fight during the friendly match between the two teams in England.
The two players clashed after a foul committed by Sergi Darder and the Portuguese player punched the Irishman in the face, who responded forcefully. This led to the end of the first half just moments before half-time.
The scuffle led to members of both benches having to rush onto the pitch to calm things down and separate the two players, who went straight to the dressing room after the violent moment during the pre-season match.
The match resumed after the break with both players being changed, after a conversation between the coaches and the referee so that both teams continued with 11 players on the pitch.
