Sweden head coach Graham Potter says he may have been bitten after arriving at the World Cup with a bloodied right ear during the team’s opening match. Potter, appointed to revive Sweden’s World Cup qualifying campaign, watched his side begin the tournament with a 5-1 win over Tunisia at Monterrey on Sunday. The match featured goals from Yasin Ayari, Alexander Isak, Viktor Gyokeres and Mattias Svanberg, with Sweden also described as defensively solid and managing the game maturely after conceding once.

Potter said he did not know what happened and that someone might have scratched or bitten him, adding that he would need to review video footage. After the result, he praised the performance and said the side had improved despite not being perfect, noting their relative lack of World Cup experience.

Separately, Potter defended Arsenal striker Viktor Gyokeres ahead of Sweden’s World Cup start, saying the 28-year-old had a “fantastic season” and that Sweden want to use his strengths to give the team a chance to win. Potter also said it remains uncertain whether Gyokeres and Isak can both start together, emphasizing that the functioning of the overall team matters.
