Despite coach Pep Guardiola resting those players for next week’s “clasico” at Real Madrid, Barcelona stayed true to its style and dominated throughout.

Sergi Roberto, a 19-year-old midfielder, scored the hosts’ opener in the 35th minute before 20-year-old defender Martin Montoya doubled the lead in the 60th. Pedro Rodriguez scored in the 63rd and capped the win with a penalty in the 88th.

Barcelona had already topped Group H while the loss condemned the Belarusian champions to fourth place.
