Spanish international Sergio Busquets will miss Barcelona's Champions League meeting with Ajax on Tuesday due to a hip injury.

Busquets has been left out of coach Luis Enrique's 18-man squad for the game as a precautionary measure in the hope he will be fit to face Real Madrid on Saturday.

His place is taken by 19-year-old Sergi Samper, who made his debut in Barca's 1-0 win over APOEL Nicosia to open their Champions League campaign last month.

French international Jeremy Mathieu is also rested, but Ivan Rakitic returns after missing Saturday's 3-0 win against Eibar.
