Portsmouth goalkeeper David James says Premiership clubs need to start investing more in their medical staff.

In his column for the Observer, James wrote: "What I can't understand is why clubs who pay out millions in wages don't invest in the best physiotherapy available. Why risk bringing a player back too quickly, only for the problems to return? If you pay £80m for Cristiano Ronaldo, wouldn't you invest £15k in his physiotherapy? The sums don't add up.

"As I see it football is once again lagging behind - physios are not up to date with the latest advances in medical care and too many appointments are still on the basis of "jobs for the boys". Factor in the pressure physios are under from managers and directors to get players back on the pitch and it's a dismal picture"
