In-form striker Erling Haaland has vowed he will only improve at Borussia Dortmund as he claimed that he is "still not 100 per cent."
The 19-year-old Norwegian starlet completed a sensational £17.1m move from Red Bull Salzburg to the German club.
And Haaland has carried over his scintillating form for his new club, scoring seven times and assisting once in his first three matches.

The Dortmund striker, who was heavily linked with Manchester United, scored a brace in his side's 5-0 demolition of Union Berlin on Saturday.
But Haland admitted that he is not at 100 per cent fitness, despite his fantastic start to life at Dortmund.
"It was pretty tough today, but it was also nice to play from the start," the Norway international told Sky Sports.
"I have to get even fitter, I am still not 100 per cent."

The Norwegian made an instant impact at Dortmund after he came off the bench and scored a hat-trick against Augsburg on his debut.
Haaland's teammate Axel Witsel hailed the wonderkid's performance on his debut and said the club have needed a "stronger striker."

The 31-year-old Belgian midfielder told the Bundesliga website: "It's crazy. To come on in the first game and score three goals, that hasn't happened since [Pierre-Emerick] Aubameyang.
"We needed a stronger striker, and the club did really good on this one. We're all happy he's here.

"I asked him how he did it and he just told me, 'I don't know, I had the feeling!'
"For his age, he's really strong. He's tall, he's big, he has a lot of quality. He can keep the ball.
"For a big guy, he's quite technical and in front of goal he's a killer."
Haaland made his first start for Dortmund against Union Berlin at the Signal Iduna Park, but he was subbed off a minute after he scored his second deep into the second half.
