Gareth Bale has reportedly been left unhappy with being made 'a scapegoat' by the club's supporters and a number of his teammates.
Bale has failed to make a sustained impact this season with just 10 goals and four assists coming from 26 outings in La Liga and Champions League, and it has led to a mixed reception from the stands.
Thibaut Courtois has also claimed that Bale has started to 'isolate himself' in the changing room, quotes which have led to further negative headlines regarding the Welshman.
According to the Daily Mail, that has left Bale frustrated at the Bernabeu and was behind his muted goal celebration against Levante on Sunday night.
However, the report adds that Lucas Vazquez - who was pushed away from celebrating with Bale - had not upset the forward in the days leading up to that match.
Bale is being linked with a summer return to the Premier League, although it has also been suggested that the 29-year-old would prefer to remain in Spain.
