Michel Platini views the hypothetic “white card” as a specific means to reproach football players for unsporting behavior. “Play-acting, criticism on the field, these are not accepted by people who love the game… This white card would send off a player for a few minutes, maybe five or 10. This would be a way to promote the game among fans who don't want to see this,” he explained as quoted by AFP.
Currently, football rules observe the yellow card for warning and the red cards for sending a player off the pitch.
Back in October, Michel Platini first proposed to introduce the white card and increase the number of substitutions from three to five, but FIFA President Joseph "Sepp" Blatter showed no enthusiasm about it.
Michel Platini is a renowned French playmaker of 1970s-80s who won the prestigious Golden Ball award three times and led the national team to the 1984 European championship.
