Premier League clubs have been told to stop their players spitting as football looks to adjust to the coronavirus outbreak.
Groups of inspectors have been sent to training grounds to ensure clubs stick to guidelines, which include the habit of spitting during play.
Though some players spit without even thinking, snoop squads have directed that players must stop in order to limit the chance of COVID-19 spreading amongst the playing squad, according to a report in The Mirror.
In addition to spitting, the report details, inspectors have also banned the sharing of water bottles and the swapping of shirts.
Some players argue that the process of spitting is needed to clear their airways, with it becoming second nature throughout their careers.
But as the Premier League looks to return with Project Restart on June 17, it has deployed enforcement officers to make sure clubs are complying with contact training regulations.
Video and GPS technology have also reportedly been used to keep an eye on proceedings at training grounds in the UK.
Professional medics have raised concerns about spitting, given it can travel so far and spread coronavirus germs.
In April, FIFA's Medical Committee chairman Michel D'Hooghe warned that footballers would have to change their mannerisms on the pitch for health and safety reasons, even arguing that yellow cards may have to be used as a deterrent.
'This [spitting] is a common practice in football and it is not very hygienic,' D'Hooge told The Telegraph.
'So when we start football again I think we should have to avoid that at maximum. The question is whether that will be possible. Perhaps they can give a yellow card.
'It is unhygienic and a good way to spread the virus. This is one of the reasons why we have to be very careful before we start again. I am not pessimistic but I am rather sceptical at the moment.'
