Sergio Aguero has signed a one-year contract extension at Manchester City that ties him to the Premier League champions until 2021.

Aguero is City's all-time leading goalscorer with 204 strikes and is in his eighth season at the club, having joined from Atletico Madrid in 2011.

The Argentina international, who has scored three goals in five Premier League appearances this season, expressed his satisfaction at signing a deal that would see him celebrate a decade at the club when it expires.

"I am happy for this additional year," said Aguero in a statement.

"My idea was being here for 10 years. I've been here for seven years, it's going to be 10 when the contract expires.

"This was the main reason I signed. I'm very happy because they have treated my very well since the first day I got here. I'm very happy with everything that involves the club, my team-mates, the staff and the management team."

Aguero has won three Premier League titles and a trio of EFL Cups at the Etihad Stadium, and his best season in a City shirt in terms of goals came in 2016-17 when he scored 33 in 45 games in all competitions.

The 30-year-old has never hidden his desire to end his career at boyhood club Independiente and gave an optimistic outlook on the club's future, picking out a number of his fellow forwards for praise as he predicted further success in years to come.

"It's true that we've got a lot of young talent, that in the future can make the difference," he said. "At the same time the youngsters are quite developed already, like Leroy [Sane], Raheem [Sterling], Bernardo [Silva] and Gabriel [Jesus].

"There are a lot of players that have got things to improve and learn, but being in this club you learn and improve faster than anywhere else.

"We have a good team, we need to be focused and if we are at 100 per cent, we have lots of chances to do great things."

Manchester City director of football Txiki Begiristain said: "We are delighted that Sergio is extending his stay at Manchester City.

"He has been so important to this club since his arrival in 2011 and he remains at the forefront of what we are want to achieve in the coming years.

"We are fortunate to have had one of the best strikers in the world at our club for so many years and I'm sure our supporters will be thrilled with this news."

Aguero could make his 300th appearance for City when they travel to Cardiff City on Saturday.
