Lionel Messi is convinced Sergio Aguero will spark Manchester City's title charge this season.
City paid Atletico Madrid £38million to sign the 23-year-old striker.
And Messi has no doubts his Argentina team-mate will be a big success in the Premier League.
Messi said: "I have no doubt that he will be successful at City.
"He will give them a real cutting edge. He's unique – he has immense power, strength and an incredible work ethic. He will certainly stand out in terms of what he will bring to City.
"Defenders will find him so difficult to play against.
"There is no doubt in my mind that City have signed a very exceptional player."
