According to reports from Spanish Channel 6, the referee who sent Bellingham off follows multiple English learning accounts on social media.
In the 24th round of La Liga, Real Madrid drew 1-1 away against Osasuna. Jude Bellingham was shown a red card for swearing at the referee. The referee wrote in the referee's report: "He (Bellingham) was just a few meters away from me and said 'fxxk you' to me." Carlo Ancelotti, however, stated that what Bellingham said was "fxxk off".
