The Blues threw away a 2-0 lead at Stamford Bridge to lose 4-2 to the League One outfit, and Mourinho was left fuming at his players’ collapse.
As such, the Portuguese has revealed that he refused to give a team-talk at full-time, such was his disdain for his side’s display.
“What did I say to the players? Nothing. Not a word. It wasn't a moment to speak to them,” he told reporters.
Mourinho refused to solely blame his players for the defeat, however, and admitted that he must take a share of the blame, despite claiming that his side “switched off” after taking a 2-0 lead.
“Do I blame myself for this? [I have] the same [responsibility] as the players," he added. "I think we should share between us. But if I am the boss, the boss has more responsibilities.
“But at half-time it was 2-1 and then we spoke about the danger of the situation. We spoke about how they play, we repeated at half-time what we spoke in the preparation of the match.
“Maybe you don't believe but we prepared in the same way we prepare for a Premier League match, the same power point presentation, same analysis, the same information, we prepare exactly the same way.
“We respect them — at least I respect them — in the way we prepared for the game but at half-time the players thought 'We are going to score, not them' and when they scored for 2-2, after that the game became crazy.”
Mourinho also batted away the suggestion that the result would force him into the transfer market, despite links with the likes of Juan Cuadrado and Douglas Costa.
“This result doesn't alter my plans in the transfer market,” he said. “I'm happy to go with the squad I have. This is Chelsea always thinking and being proud of thinking of numbers and Financial Fair Play and so on.
“We cannot now go to the market and spend money. I am completely with the club. I share this idea. I don't think we are going to the market, unless someone makes a market with us.”
