Barcelona and Bayern Munich will miss key players when they take on Napoli and Chelsea, their respective opponents, in the Champions League round-of-16 second leg clashes on Saturday.

Barca, who will be without midfielders Sergio Busquets, Arturo Vidal and Arthur, will bank on youngsters Ansu Fati and Riqui Puig as possible replacements. With Lionel Messi and Luis Suarez set to start in attack, Fati could get picked over Antoine Griezmann.

Barcelona drew the first leg 1-1 in Napoli.

Bayern will be without winger Kingsley Coman after the Frenchman picked up a muscle injury. Coach Hansi Flick said Coman would be replaced either by Ivan Perisic or Philippe Coutinho.

Chelsea too have quite a few injury worries. Bayern won the first leg 3-0.
