Have you considered that your groin pain might have its origin in your Thoracolumbar region? Check this and retest the groin movements. Additionally, many footballers I see with groin problems sit in lumbar flexion and laterally rotated hips. They attempt to run and kick a ball in this position and therefore stress the groin. You need to change how you sit and run and then see what happens to the symptoms.
