The Netherlands striker Vivianne Miedema will miss her team’s Euro 2022 Group C clash with Portugal after testing positive for Covid-19. Miedema, who is the all-time top goalscorer for her country, will isolate for “the next few days”. The Arsenal forward’s absence is the latest in a number of injuries and illnesses that have hit the Dutch squad since their 1-1 draw against Sweden. Midfielder Jackie Groenen is also isolating and the defender Aniek Nouwen is expected to miss the game at Leigh Sports Village due to an ankle problem. The captain, Sari Van Veenendaal, is out for the rest of the tournament with a shoulder injury. With the standings all square in Group C after two draws in the opening fixtures, the defending champions will come up against a resilient Portugal team who bounced back to draw 2-2 against Switzerland. The Portugal head coach, Francisco Neto, knows his side cannot afford mistakes if they are to pull off an upset. “We need to start super-focused on our jobs; at this level, mistakes will be punished,” he told uefa.com. “Against experienced teams, used to these games, with players with huge talent, we need to be fully focused and try to negate the attacking talents of the Netherlands. There’s only one way to do that – have the ball and keep the ball. That’s our mission.”
