Lionel Messi scored twice as Barcelona wrecked Marcelino’s first match in charge of Athletic Bilbao with a hard-fought 3-2 triumph at San Mames.
Inaki Williams made an instant impression on Athletic’s new manager – appointed following the dismissal of Gaizka Garitano by scoring inside three minutes for the home side on Wednesday.
Teenager Pedri equalised with a header soon after, and a powerful first-time shot from Messi made it 3-1 and Barcelona held on for the victory, despite a late 20-yard strike from Athletic’s Iker Muniain.
