Ex-midfielder Manchester United Roy Keane offers an alternative to those who are afraid of injury in football.

Ex-player of the national team of Ireland Kevin Doyle recently announced his retirement due to the fact that he received in football concussions can cause serious damage to health.

But Roy Keane, who had a reputation as a tough and uncompromising player, believes that players must accept the dangers of sports.

"I think there are studies devoted to brain concussions. Who is afraid of injuries - let him play chess. Injuries - part of the game, no matter it's throwing a drive or American football, "- quotes Roy FourFourTwo.

"Look at the guys who play rugby. When they cross the line, they take a risk. There is a chance that they will be hurt, but this is the game ".

"I was surprised when I read about the end of Doyle's career. It's sad, but he thinks he made the right decision. This is a great guy who played great for Ireland. He is already 34 and, probably, now is the right time. As they say, your health is your wealth ".

"I read that he had a concussion or two. On the football field there is always a risk and Kevin decided that it would be right. But injuries - this is part of football, players are constantly getting them. He is a center forward, so he gets away from the defenders - I think, and from him too, because football is a physical game ".

Injury is not afraid, for example, goalkeeper Manchester City Ederson. Brazilian in a clash with the winger of Liverpool Sadio Manet got so that he left the field on a stretcher. Nevertheless, Ederson said that this will not affect his style of play in any way.
