Despite Real Madrid struggling to put the game to bed, Ancelotti decided against freshening up his team and give fringe players an opportunity.
As a result, Eden Hazard, Marco Asensio and Marcelo were three players who were not happy with the way they were treated, with the first two not being used to playing so little.
Meanwhile, Marcelo has not been given much playing time this season either and he wasn't pleased that he had to warm up for 40 minutes without eventually taking to the field.
Ancelotti was aware of the situation and he apologised to his players after the final whistle was blown, as he acknowledges that part of his job is to handle complicated issues such as frustrated players in the dressing room.
