Watford were left chasing a goal deficit from the fourth minute after Salah prodded his side ahead.
Looking for a goal, Pereyra produced an awe-inspiring flash of brilliance. Trapped by Mane in the corner, the Argentine chopped the ball through the Liverpool man's legs and burst into the box.
Mane didn't know what hit him as he stood stunned. Keep your legs together next time, Sadio.
