Sergio Aguero agrees Manchester City contract extension - Pep Guardiola

MANCHESTER, England -- Pep Guardiola has confirmed that Manchester City striker Sergio Aguero is set to sign a contract extension.

The Argentine striker has agreed to extend his current deal one year to keep him at the club until 2020, a source told ESPN FC.

Guardiola said he expected a deal to to be officially announced by the club.

"I don't know if I am the right person to talk about that but I think he is going to extend the contract, but it is not official," he told a news conference. "I am not the right person, I don't know if it is definitely going to happen. That's all.

"I think he is a good player. I think there are players you want to stay and still they have the patience to play in this club. So, we cannot discuss about his quality. If he stays I will be so, so happy."

Aguero, 28, had said he would rejoin his first club Independiente at the end of his current deal in 2019. However, the Argentine will remain at the Etihad for a further year, and a source said the extension was agreed in principle in January.

Aguero has started this season in fantastic form, scoring nine goals in five games, including two hat tricks in the Champions League already, and he said he expects to score even more goals under new City boss Pep Guardiola amid the side's perfect start to the season.

"I'm really happy with the new manager," he told reporters after City's 4-0 victory over Borussia Monchengladbach on Wednesday night.

"According to my style of playing, he is one of the managers that have helped me most in my career. Despite [my form] in the Premier League, and my last season at Atletico, I've improved in my game near the box and scoring goals. With Pep I will get even more chances.

"I'm really happy with the way we have started the season. It's always important to start playing good at home."

Aguero, who joined City from Atletico Madrid in 2011 for £38 million, has scored 145 goals in 213 appearances for City.

He has scored more times in the Premier League than any City player and needs another 34 goals to become the club's greatest-ever goal scorer by overtaking Eric Brook, who scored 178 in the 1920s and 1930s.

Aguero became the youngest player in the history of the Argentine top flight when he made his Independiente debut in 2003 at just 15. He scored 23 goals in 56 games for them before moving on to Atletico in 2006.
