The PFA Pitch Rating System is back for its second season as the players' union strives to prevent its members from suffering injury on inadequate playing surfaces.

The system was introduced at the start of last season after players voiced concerns over the state of A-League pitches.

Last season, Brisbane Roar's Suncorp Stadium set the benchmark for A-League pitches finishing in first place  while Newcastle Jets' Energy Stadium was rated the poorest.

At the conclusion of each A-League match, the visiting captain rates the pitch by assigning a mark out of 5 on 4 criteria: (1) overall; (2) hardness; (3) pace; and (4) smoothness.

"In short, the results illustrated that while some clubs were meeting the standard required for top-tier professional football, others needed to be improved in order to ensure player health and safety," said a PFA spokesman.

"In order to continue the growth and success of the A-League, it is crucial to protect the health and safety of the A-League's biggest asset - the players.

"Clubs and competition organisers have a responsibility to ensure the wellbeing of players by providing a work environment which is free from unreasonable risk to their health and safety.

"The system brings accountability to this area which is of fundamental importance to players."
