The number of COVID-19 cases growing around Europe is also impacting the world of soccer. Valencia confirmed four cases on Monday, including their head coach and two players. In England, 42 Premier League players and staff tested positive in the past week - the most recorded in the league over a seven-day period. An outbreak at Tottenham Hotspur led UEFA to postpone their Europa Conference League game against French side Rennes last week.
