You ask a 17-year-old kid, of course.
That's what Parma did just over 20 years ago when European heavyweights Milan rolled into town in 1995.
Yes, Gianluigi Buffon was to get his Serie A debut against a side that dominated the 1990s.
It's a game manager Fabio Capello remembers well, explaining he was looking at the team sheet in the dressing room and wondered out loud why his opponents were fielding a goalkeeper barely out of the academy.
"After the game, I understood the reason for that choice," he told Gazzetta dello Sport when asked about the 0-0 draw.
"Buffon helped Parma with three extraordinary saves," he added.
Four saves, according to the goalkeeper's dad, Adriano, who sat nervously in the stands that day as his son began his trophy-laden career.
"He made a bad mistake and the guy sitting behind me said: 'Children should not play in certain matches'. I immediately hit back: 'Look at this kid, he will play in the national team in five or so years.'
Buffon, who turned 38 in January, actually went on to play 154 times for Italy and is still the no.1. In addition to the countless domestic silverware, he is also a World Cup winner.
“It all turned out well in the end," his old man went on. "He stopped Baggio and Weah and made four important saves at different situations.
"Even today I tell my son that he has never parried better than that day at the Stadio Ennio Tardini.”
