Manchester United striker Michael Owen says it's getting tougher to make it in football.

Owen feels the demands on players mean only a certain type of athlete is going to succeed.

He told Inside United: "It's never been easy to make it as a professional footballer and it's not getting any easier. These days football is very athletic as well as skilful - you need the right sort of body to cope with the rigours of the game. You also need to be quick, or you'll be left behind. You need to be confident and calm on the ball, and have a good reading of the game. You need an awful lot to succeed. But don't let that put you off!"
