Premier League players are being encouraged to get vaccinated while on international duty in what could develop into a clash between club and country.
While managers such as Jurgen Klopp and Marcelo Bielsa have been proactive in urging their players to be jabbed, others have been more cautious, as even mild side effects could lead to their stars missing matches.
The two-week international break is being viewed as an opportunity to increase vaccination rates by some clubs, causing tension with international federations reluctant to lose players for World Cup qualifiers.
The FA have indicated their willingness to facilitate vaccination among the England squad by taking them to appointments if required, but they do not have a vaccination centre at St George’s Park.
