With about 20 minutes left of the match, Mourinho walked to the sideline and began yelling at referee Anthony Taylor after he asked Branislav Ivanovic to speed up taking a throw-in.
The Portuguese manager was apparently incensed at Taylor’s request after Cardiff, who took an early 1-0 lead, engaged in time-wasting of their own without repurcussion.
Taylor pointed Mourinho off the pitch, leading the 50 year old to take a seat in the stands next to a fan. Mourinho remained there for a short while before being told by an usher to exit the match, which he complied with.
