Former Manchester City star Sergio Aguero says Erlin Haaland must learn from his performance in the Community Shield.
The 22-year-old Norwegian started the match, which saw Liverpool win 3-1.
Haaland had a gilt-edged chance, though blew it.
Aguero said, “Haaland is too accustomed to Germany.
"He thought he would be alone, and then (Virgil) van Dijk told him: 'Welcome to the Premier League'."
