These times are really tough times. Because of the new variant of covid-19, the games in various leagues started being postponed one by one. There are so many footballers who are having this illness currently. It is really bad for Tottenham especially. Because so far, their three official games in total have been postponed like this one. They can have a really tight fixture in the future.
What is feared really happened, after we all started to feel safe from COVID-19, it turned out that this virus showed that they still existed even though most of the world had already received the vaccine. The case of this new variant of COVID-19 could cause all leagues to be stopped again, because based on research, this new version is resistant to currently available vaccines.
Gerrard seems to be taking quick steps to prevent his players from being exposed to COVID-19, he will consider seeing the vaccine status of the target players. Maybe other coaches need to follow this way, so players don't underestimate the vaccine (if there are still football players who haven't been vaccinated)
