The 52-year-old has made it clear that the youngster is not Milan's only dangerous forward, and has warned his team not to underestimate their opponents
The 20-year-old has been the San Siro side's standout performer so far this season with 14 goals in 19 Serie A appearances, but the 52-year-old has insisted that his next opponents are not a one-man team.
"When you're up against teams like Milan, it's not enough to stop just one element. If we stop El Shaaraway, there's still Robinho or Bojan [Krkic]," the Sampdoria coach said at a press conference.
"I don't think Milan will be tired after the Coppa Italia game against Juventus as they're a team used to playing every three days. It's not a physical question, it's a mental one and they're used to playing midweek.
"If we think it'll be easy against Milan at home because we beat Juventus away last week, that would be an unforgivable mistake and our league position doesn't allow us to make mistakes."
Milan are currently seventh in Serie A, with Sampdoria a further seven places behind them.
