Technology that could ruin or improve football?

An earpiece was tried in cricket. Bob Woolmer gave a mike and earpiece to the on field captain when coach of South Africs but was banned almost immediately by ICC. I think part if the beauty of sport is to test players tactical intellengence under pressure that should not be taken away.

I thought that the Aussies had used the same technology in a test match before it was banned.
