As we previously highlighted, three more soccer players in the space of one week experienced chest pains or shortness of breath and had to leave the field of play.

Manchester United's Victor Lindelof, Napoli midfielder Piotr Zielinski, and Martin Terrier of French club Rennes were all sidelines with heart and breathing disorders.

"It's been very concerning for me watching the sport that I love and I played for 17 years…in all that time that I played I never once saw any footballer leave the pitch because of heart issues," said Le Tissier.

"Now I'm sorry, but if anybody can look at what's happening now in the world of sport and say it's normal for all of these people to be having heart issues, in football matches, cricket matches, basketball matches, any sport you wish, these people, the amount of people that are suffering is going through the roof," he added.

Le Tissier says he is calling for an investigation with the caveat, "It might not be to do with the vaccine, it may not be, but let's have an investigation to find out what it is."

"Even saying that deems you to be some kind of anti-vaxxer, which is absolutely disgusting," said Le Tissier, referring to the treatment of people who dare raise the issue.

"I want just some information, I want people to take a look at what is happening in football, have a proper investigation and give us some answers as to why so many sports people are suffering with heart issues – it's not difficult," he concluded.
