'Will take a while' - Aguero explains when fans are likely to see results from Haaland

The striker completed a blockbuster move to the Etihad Stadium earlier in the summer, with City snapping him up in a £51million deal from Borussia Dortmund.

The 21-year-old is regarded as one of the top attacking talents in world football, scoring 85 goals in 88 appearances for the Bundesliga side, and is expected to hit the goal trail for the Premier League champions.

Aguero is a true City legend after spending 10 years at the club between 2011 and 2021, a period in which he racked up 259 goals in 388 appearances.

According to the Argentine, Haaland will need time like everyone else to adapt to the demands of life under manager Pep Guardiola.

Writing in his blog on stake.com, Aguero said: "Haaland's is a very important signing.

"I think his goalscoring ability is proven. His stats through the German league and in Europe confirms this.

"Logically he will have a period of adaptation to a league as strong as the Premier League but I think he will go through his own process and the results will be seen soon.

"I think that an elite player like him will know how to reconcile his style with that of Pep's teams.

"It may take a while, as it did in the beginning for me.

"But once he gets into gear everything will be simpler. I think he has the talent to fulfil what is asked of him, which are goals."

Haaland is currently excelling in training as he gets himself up to speed for the big kick-off next month.

City begin the defence of their crown with a visit to West Ham on 7 August. Before that, though, they play Liverpool in the Community Shield on 30 July.
