Manchester City's signing of Gabriel Jesus was like buying a watermelon, said Pep Guardiola after the Brazilian teenager's first goal for the club.
The 19-year-old, who joined from Palmeiras, scored one and assisted another on his first Premier League start as City thrashed West Ham 4-0.
"You never know. It's like a watermelon. You have to open to see if it's good or not," said boss Guardiola.
"The prospect was good. He's a young player. But he's had a huge mentality."
City signed the striker in the summer for £27m, but he spent the rest of 2016 with his Brazilian club - helping them to win their domestic title.
