Lionel Messi scored in his first game since trying to leave Barcelona as Ronald Koeman began his tenure as coach by overseeing a 4-0 La Liga demolition of Villarreal on Sunday.

Messi converted from the spot 10 minutes before half-time and it was the Argentine's cross that then forced Pau Torres into an own-goal, after an early double from Ansu Fati, 17, had already put Barca in charge.
