Benfica boss Bruno Lage challenged Joao Felix to become more consistent and warned against treating the teenager like a "superhero" following his record-breaking Europa League hat-trick.
Teenage attacker Felix became the youngest player to score a treble in the competition's history on Thursday as he inspired the Primeira Liga leaders to a 4-2 victory over 10-man Eintracht Frankfurt in the first leg of their quarter-final tie.
The 19-year-old also tallied an assist for Ruben Dias' second-half header in a brilliant display that is sure to have alerted the heavyweight clubs that are believed to be tracking his development.
