Hypothetical Dogfight EE Lightning v Mig21

I have a question for the boffins here. If an EE Lightning were placed into a dogfight with a Mig21 what would the outcome be? Both aircraft have a basic radar, short range AAMs and a cannon. The Mig21 bleeds off airspeed in a continuous tight turn. The Lightning has short legs. Both are Mach2 jets.

I know that pilot training between the RAF and WARPAC airforces varied but for the sake of the argument lets say that both pilots are of equal caliber.

Let the bunfight begin.
