Liverpool centre back Virgil Van Dijk has conceded he does not know how he can stop Barcelona's Lionel Messi when the two sides come face to face in their Champions League semi final next month.
Van Dijk is considered by many to be the best defender in the world, but even he appears unsure how to tackle the threat of the Argentinian superstar, such is Messi's ability to conjure moments of pure genius when scoring and creating goals for his team.
Barcelona's No.10 was once again the difference as they progressed 4-0 on aggregate in their quarter final against Manchester United, scoring twice at the Nou Camp on Tuesday night to take the game away from Ole Gunnar Solskjaer's side.
