Requirements for singles.

What are the requirements to be a good singles player ?? My opinion in no particular order except No 1.

• Discipline
• Good footwork and movement
• High level of fitness
• Mental strength
• Able to hit the shuttle from anywhere in his court to anywhere in his opponents court.
• Strong smash
• Commanding at the net, killer instinct...not passive
• Obviously to have a good all round shot selection in all situations
• A thinking mind, strategic and always has plan A, B and even C when needed
• Physically, strong calves and quads with a slim torso are preferable.
