Thomas Tuchel believes the "edgy" atmosphere inside Old Trafford during Chelsea's 1-1 draw with Manchester United benefitted his side.
There were plenty of empty seats inside the stadium at kick-off as fans continued to protest the ownership of the Glazer family outside.
Once those supporters filled in after 17 minutes there were regular chants against the Glazers, while Chelsea's dominance of the game also caused some murmurs of frustration around the ground.
