Premier League clubs are lagging behind the world's major sports in persuading its star players to get the Covid-19 jab.
A Mail on Sunday survey has found that almost all other top leagues have a much higher vaccine take-up rate than English football.
Even tennis – which has had a similar issue with vaccine hesitancy - is threatening to outstrip English football, with the take-up rate on the ATP Tour having improved by around 20 per cent over the past six weeks.
Rival sports have attributed their success to reasons that include top athletes promoting the jab and tougher restrictions for unvaccinated players, neither of which have happened in the Premier League.
