Mourinho's men wasted a chance to keep the pressure on Premier League leaders Arsenal as Oussama Assaidi's last-gasp goal condemned the Blues to a frustrating loss at the Britannia Stadium on Saturday.
With Arsenal in action at home to Everton on Sunday, Chelsea could be seven points off top spot by the time they return to domestic action against Crystal Palace next weekend.
But Blues boss Mourinho could point to Manchester United's defeat against Newcastle and Manchester City's draw at Southampton as proof that Chelsea aren't the only ones in erratic form at present.
"I think we are doing well," he said. "To be there, where we are, you see us in relation to Manchester City, Manchester United, Tottenham and Liverpool and we are not doing bad, even in term of points in the league."
Mourinho maintained his relaxed approach at the end of a week that saw Chelsea concede six goals in two matches.
While his players wasted a chance to close the gap on Arsenal, Mourinho still gave the squad a rare day off afterwards in the knowledge that their December schedule will be hugely demanding.
