"We never understood this and we said before that we could not understand because both teams are involved and it would have been easier for both teams to have had a Wednesday game because the next game is Sunday," Tuchel said before the pre-match at Stamford Bridge.
"There is absolutely no reason to play Saturday, Tuesday, Sunday. It is absolutely logical to play the game on Wednesday.
"From a sporting side, nobody can disagree. But, okay, we were surprised we could not change and we cannot wish for another date to play, so we will be ready tomorrow."
