Manchester City manager Pep Guardiola admits even he is surprised by the stunning start Brazil forward Gabriel Jesus has made to his career in English football.

The 19-year-old scored twice on his full home debut as City recorded a 2-1 victory over Swansea City on Sunday, meaning the youngster has scored three goals on his first two starts in the Premier League.

After arriving in England at the start of last month, Jesus is emerging as one of the most exciting prospects to land in the English top flight for some time.

"Yes, I'm surprised," said Guardiola, whose side climbed to third place in the table, 10 points behind leaders Chelsea.

"When he came here after he finished the season and won the (Brazilian) championship with Palmeiras, we spoke.

"The last two or three years he never had a break because Brazil played a lot of games. I said, 'Take your time, come back when you feel you're ready.'

"But he's 19 years old, Brazilian guys are physically strong and he only needed a few training sessions to be ready.

"The guy told me he is never tired, always healthy and recovers quickly. We need to protect him, but everybody is surprised at his level."

Jesus opened the scoring in the 11th minute with a close-range volley and gave City victory in stoppage time after Gylfi Sigurdsson had levelled with nine minutes to play.

"In the box, he is something special with the ball," Guardiola said.

"It is clear how his first touch is good. With his second, third, he needs to improve, but without the ball he is involved.

"He is so intelligent, knows when to put pressure on the central defenders.

"Some guys need a lot of time to settle, to know the league, the teammates, and others (settle) immediately, and that guy arrives like this."

Jesus revealed at the weekend that a personal phone-call from Guardiola helped make up his mind to join City in a £27 million move that was completed last month.
