Last weekend's shock 1-1 draw at bottom club Almeria, which left them four points adrift of leaders Barcelona, was hardly the best preparation for Sunday's potentially tricky La Liga clash at home to Real Mallorca.
Goalkeeper and captain Iker Casillas moved to quosh the reports about Mourinho's possible exit, which came the same day the club clashed with Spain's football federation (RFEF) over an article on the RFEF website that mentioned Mourinho.
"He wants to stay and (the club) wants him to stay," World Cup winner Casillas said in a radio interview on Wednesday.
"I am saying that and I am the captain," he added. "We have a young team and he (Mourinho) knows that it can bear fruit over the long term. He is delighted with the city and with the club."
They were responding to an article saying the referee for Real's King's Cup match at Atletico on Thursday would be "under the close scrutiny of Mourinho, who feels he has been mistreated by officials in recent league matches".
He has also expressed frustration at the club's failure to find a replacement for injured striker Gonzalo Higuain and local media have reported his relationship with director general Jorge Valdano has become strained.
Mallorca, coached by former Real midfielder Michael Laudrup, will be depleted by injury and suspensions on Sunday but are no doubt hoping their opponent's off-field distractions will improve their chances of causing an upset.
Barca booked their place in the last four of the King's Cup on Wednesday despite having their club record 28-match unbeaten run ended by second-division leaders Real Betis.
"It takes a lot to go 28 matches without losing," Guardiola told a news conference. "We have to lose to appreciate things. This result shows how hard everything is and was good for putting us in our place."
