Chelsea fans has been urged turn up volume on Wednesday night by Tuchel.
The Blues will be welcoming Real Madrid for their quarter-final first-leg tie of the Champions League tonight.
Thomas Tuchel wants the crowd to give some extra motivation tonight at the Stamford Bridge.
Both the teams met each other last year in the Champions League semi-final tie.
“We absolutely need it,” the German said.
“We need to be better on pitch but we also need the crowd to be better. Everyone has to be on the front foot for a big opponent on the big occasions.
“ We normally have these atmospheres in evening games and big matches. In the Champions League matches they gave us a huge push in energy and atmosphere. It is crucial in these games. It’s much harder to play against the spectators as well. We felt it in Malmö and St Petersburg. We will face it again in Madrid next week and everyone needs to arrive tomorrow to support us.”
