The lightly-dressed daredevil was described as “sexy” by some fans as they spotted her casually making her way to the halfway line during the game at the Gazprom Arena.

She was soon willingly marched from the pitch by stewards, with some fans complaining that the cameras had cut away from the eye-catching action.
