Palerma’s defeat to Bologna left them without a win in six Serie A matches, leaving them out of the Champions League group stage.
The Giallorossi, who are third in the table, had to play in front of a sellout crowd of 18,500.
Palermo coach Antonio Conte has said that the defeat left him “very upset” and will not be playing at home for the rest of the season.
“It was not good for us.
I am not sure what happened.
I had no time to think, so I just felt very upset,” Conte said.
He is hoping to bring in a replacement for the injury-hit Giorgio Chiellini and said he will also look to get more players fit before the end of the month.
Injuries are a concern for the Italian champions as they have lost only one of their last six matches.
With their home game against Sassuolo scheduled for March 4, they are looking to bounce back from the Champions.
Pellegrini will look to extend his side’s unbeaten run at the Camp Nou to seven matches with a win against the Nerazzurri.
Conte has also made it clear that he will not use his last game as manager as the start of his tenure.
There is also speculation that he may be forced to resign if the Nerazu’s season collapses.
If he does not, Conte will be forced out of his job.
The Bianconeri are currently seventh in the Serie A table with nine points from five matches.
