City's new number nine Erling Haaland throws early dig at Manchester United

The Norway international, left Borussia Dortmund for Manchester City - the club his father Alf Inge previously played for - in a deal worth £51million and was formally unveiled to the fans on Sunday afternoon.

When asked who he wants to play the most next season he replied: "I don't like to say the words, but Manchester United." The watching crowd cheered and burst into chants of 'City, City, City.'

The 21-year-old does not feel any pressure joining the Premier League champions and intends to enjoy himself.

Asked how he would approach the challenge he said: "Like I have been doing my whole career, try to enjoy every single minute, every moment, try not to think too much.

"Overthinking is not a good thing for every human being. I just try to relax when I can and work hard."

On what he would bring to the Premier League, Haaland added: "Hopefully some more quality with me as a striker I want to have fun, when I have fun I score goals, I smile, I enjoy playing football, I smile a lot."

When he was told he was already the favourite to be next season's Premier League top scorer, the Norwegian said: "The most important thing is to enjoy."

Haaland inherits the City number nine shirt vacated by the club's all-time leading scorer Sergio Aguero, who left last summer for Barcelona only to be forced into retirement by a heart problem.

It is a shirt which is familiar to him as he already has a match-worn shirt given to him by the Argentinian.

"He is a legend, one of the best ever to play in the Premier League and I remember a lot of goals he scored, especially the 93.20 goal (which won City's first Premier League title in 2012), so I remember a lot of goals from him."

Haaland is keen to follow in his footsteps and lay down a legacy at City after a rapid rise which has seen him join his fifth club in almost six years.

"I signed a five-year deal so we have to start there," he said when asked if now was the time to set down some roots.

He does not, however, believe his progress is ahead of schedule.

"In some ways but also not when you see how I have been performing," he said.

"It was a big step going to Molde from my hometown club, it was a a big step going to Salzburg, Dortmund and now City but it has been going good."

While City have been dominant domestically, winning the Premier League in four of the last five seasons, the Champions League has remained out of their reach.

Haaland was asked if he was the answer to City's so-far fruitless quest for European club football's biggest prize.

"I said it before, the Champions League is my favourite competition, so you have the answer there," he added.

"It is a big challenge, it is a new country, a new league, new coach, new everything, so it is a big challenge but I know how it is to come to a new club, I have done it a couple of times before. I am really looking forward to it.

"I played against them in the Champions League last year and you see something on TV and then when you meet it is completely different.

"I didn't touch the ball for 25 minutes and it is like '(Ilkay) Gundogan please stop playing tiki-taka'.

"It is a different level how they play and that is what I want to be a part of."

Haaland has already made an impression on one of his new team-mates, goalkeeper Stefan Ortega, whose Bundesliga experience with Arminia Bielefeld means he has been able to watch his development at close hand.

"His transition is really outstanding. When I saw him in Salzburg he was a bit thin, now he's a monster, with his size, speed, quality in shooting and heading, he's the full package that you can get," said the 29-year-old, who has arrived as back-up to Ederson.

Haaland is not the only new forward to join up for pre-season training this summer, with Argentinian Julian Alvarez also arriving from River Plate having been loaned back to the Buenos Aires club after signing a deal with City in January.

"Manchester City has a lot of history with Argentinian players. I came here to create my own history, create my own path and help City reach the top and continue the success it has been having," said the 22-year-old.
