The tension of the defeat to Fiorentina spilled out with Barbara Berlusconi urging her father, President Silvio Berlusconi, to revamp the way the club is run.
"I won't comment on these things," replied Allegri. "The players and I must focus only on the field, reaching the next phase of the Champions League and climbing the Serie A table.
"We are doing well in the Champions League and cannot waste what we've done so far. In Serie A, we need to improve in order to get back up the standings.
"We've worked together over the last few days and you can't emerge from a crisis in one match, but the fundamental thing now is to push luck our way.
"Playing against Barcelona brings great motivation to anyone. It will require the perfect performance."
