If people have been telling you that you are special since you are ten years old, which will be the case for many footballers, I think the result can be that you feel are knowledgable about a lot of things which you know Jack shite about. Look at how many even of today’s top footballers end up bankrupt.
So a tendency to think you know it all, a tendency to follow social media as “the news”, a feeling that you are invincible fitness wise, may all be factors.
But while they are all factors, the last point is that there’s no excuse not to get vaccinated. If those figures quoted above are correct, there must also be a question about the difference in approach between clubs in England to those in Italy and Germany. Football in Italy has always been seen as a serious profession and players are expected to look after themselves in a professional way. It may be their clubs are putting pressure on their players, whereas in England clubs are more relaxed.
