Erling Haaland has vowed to become "even better" once he has fully settled in at Manchester City after scoring his first Premier League hat-trick.
The 22-year-old scored a couple of poacher's finishes before clinically completing his treble as City recovered from two goals down to beat Crystal Palace 4-2 on Saturday.
Haaland scored three Bundesliga hat-tricks for Borussia Dortmund before joining City last month and wasted no time in securing his first for the Premier League champions.
He is the fourth player to net at least six goals in his first four Premier League games, and the first to do so since Diego Costa netted seven for Chelsea in the 2014-15 season.
While Haaland has hit the ground running at the Etihad Stadium, the Norway international ominously warned there is more to come in a stark warning to defenders.
"Of course it takes time but I know it will come and get even better. It's not easy to come to a new club, a new country so it has been a good start," he said.
"It was a really good feeling to turn the game around. We had the mentality to trust each other and keep going.
"It's about trying to continue what we are doing. It was about small adjustments and we did that and got results. We had to listen to the manager."
The win over Palace marked the first time City have recovered from two goals down at half-time in a Premier League game at the 54th attempt.
A John Stones own goal and a Joachim Andersen header had put Palace in control.
But Bernardo Silva instigated City's latest comeback in the 53rd minute and Haaland took over with his 19-minute treble in just his second home outing for the club.
Now on six goals for the season, Haaland joked his next target is chasing down father Alfie's tally of 18 - scored with Nottingham Forest, Leeds United and City.
"It’s a proud moment for me and my family," Haaland said. "But my dad will probably say he had more goals in the Premier League than me so I will chase that."
