Manuel Pellegrini says that Manchester City's Sergio Aguero has not hit the top of his game yet.
The Argentine striker is joint top of the Premier League scoring charts with nine goals in the league already this campaign, but he has not reached his best form according to his manager.
Agüero has scored five goals in his last two games in all competitions, and 11 in total, but Pellegrini clearly feels that there is still more to come.
"I don't think it's the best I've seen from him," the Chilean boss said to the Daily Mail. "I know him a lot of years before he arrived in England when he played back in Spain.
"And in Manchester City's 2011-12 when they won the title he was a very important player. Last year, he was very important when he was not injured. After that it was difficult for him, but that's normal. I was always sure he would return to normal performance.
"He's a young player, he has a lot more years to improve, it depends what he wants to do in future. He has all the conditions to do it."
It is a warning sign to the rest of the top-flight that Pellegrini feels that Aguero isn't at the top of his game.
The 26-year-old has torn apart defences already this season and if he isn't in top gear then he is set to cause more damage during the rest of the campaign.
Aguero is widely considered the best striker in the Premier League, but his struggles with injury have stopped him truly reaching his potential.
If he can stay injury free for this campaign his goalscoring exploits could be truly incredible, especially if Pellegrini's words are true.
Aguero's next game with City will be against West Ham United, where he will be trying to continue his form and fire his side to three points.
