The Bianconeri fans were not pleased with the performance of the 25-year-old during their goalless draw with Lazio in Turin in Serie A.
"There can be dissent, but I'd like to underline it was a small section and not the entire stadium," Claudio Pasqualin told TMW. "Seba's time at Juve has been positive and the proof is there in the fact [coach] Antonio Conte considers him to be a first-choice pick.
"Maybe he could've scored a few more goals, but he is aware of that too. At times it was down to bad luck, others the opposition goalkeeper, but Seba is relaxed.
"He has a cool head and the strong shoulders of a champion. This unlucky moment will pass. As for the jeers, even if they were coming from a small minority, it is all part of the game."
Juventus are currently at the top of the Serie A table with 32 points from 13 matches.
