The official's post-match antics irritated the Blues' manager.
Yesterday, against Real Madrid at their own ground, the Blues produced some of their best football.
After 90 minutes, they were able to defeat Madrid 3:1, but the aggregate score was 4:4.
After extra time, Real Madrid won 3:2 and advanced to the next round of the competition.
According to Thomas Tuchel, the referee response to Chelsea was far worse than that to Real Madrid.
Following his team's 5-4 aggregate loss to Real Madrid in the Champions League quarter-final, he accused referee Szymon Marciniak of inappropriate conduct.
Following the second match, the German coach alleges Marciniak was overly friendly with Blancos coach Carlo Ancelotti.
