Not just in football man. There are plans to scan all kids in secondary schools, basicaslly as mandatory as the TB injection.
Basic heart trace would do. I had one about 3 years ago, when I was 18/19. Took about 15 minutes, max.
I would be very surprised if that didn't already form part of a footballer's medical.
Other sports though have mandatory and extensive tests for every participant that take place before every event, and have a huge team of independent medical experts who can stopsportsmen from competing if they fail these tests.
This would also allow for better drug testing.
Footballers should have independent medicals every month in my opinion, bringing it into line with other intensive sports.
