Cristian Brocchi prepares for Lazio's Champions League showdown with Napoli and concedes “their enthusiasm frightens us.”
The two sides are battling for a top four finish, although technically the Vesuviani are still in the Scudetto race too.
“The thing that frightens us the most is their enthusiasm. The San Paolo will be absolutely packed to the rafters,” Brocchi told Lazio Style Radio.
“They'll be eager to beat us because it would be a hugely important result for them and really break away from the chasing pack.
“We must do well and, above all, work with a great deal of confidence in that hostile environment.”
The match kicks off at 11.30 UK time on Sunday April 3.
