The Blues suffered a shock 2-1 loss to FC Basel in their opening Champions League fixture at Stamford Bridge on Wednesday night making it two defeats in a row (three if you count the UEFA Super Cup penalties loss to Bayern Munich) after Saturday's 1-0 reverse at Everton.
After the match, Mourinho shouldered all the responsibility, saying it was he was accountable for the current poor form of his side.
"I am the manager, I am responsible for everything," he told Sky Sports 1.
"Especially after a bad result. In the good moments I want everyone to shine, in the bad moments I want everyone to keep calm.
"Tomorrow I will not wake up with a smile on my face but at seven o'clock I will work hard to get three points at Fulham. In the next match we go to Bucharest (in the Champions League), we have to get the points to put us in the Champions League. We don't want to play in the Europa League."
He added: "I not in shock because sometimes we win, sometimes we lose.
"But I am not happy. We gave one step back for qualification and we have to assume the responsibility that we have five matches to qualify."
