Manchester City striker Sergio Aguero has signed a one-year contract extension that will keep him at the club until June 2021.
Aguero, City's all-time leading scorer with 204 goals in 299 appearances, moved from Atletico Madrid in 2011, and the new deal means he will be at the Etihad Stadium for 10 years.
He signed a five-year deal in 2014 and a one-year extension in summer 2016, and will be 33 when his contract expires.
"I am happy for this additional year," Aguero said. "My idea was being here for 10 years. I've been here for seven years [and] 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 teammates, the staff and the management team."
Aguero has been linked with moves away from the Etihad since the arrival of Pep Guardiola but finished last season with more than 20 Premier League goals for a fourth successive campaign.
He had a knee operation at the end of last season and said he is playing pain-free for the first time in years.
"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," director of football Txiki Begiristain said. "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."
City have tied down a number of key players to new contracts in recent months with Kevin De Bruyne, David Silva, Gabriel Jesus, Fernandinho and Ederson all signing new deals.
The club are also hoping to secure new contracts for Leroy Sane and Raheem Sterling, with the latter in the final two years of his deal.
"It's true that we've got a lot of young talent that in the future can make the difference," Aguero said. "At the same time, the youngsters are quite developed already, like Leroy, Raheem, Bernardo [Silva] and Gabriel.
"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 percent [and] we have lots of chances to do great things."
Guardiola, who also signed a contract extension keeping him at the club until 2021, is delighted that Aguero is decided to stay for another 12 months.
"I didn't convince him, he decided for himself so that's why I say thank you so much for trusting in us," Guardiola told a news conference. "At the end, players like him, Vincent [Kompany] and David [Silva], they decided because they show it every day in training and off and on the pitch, there is a commitment to our club.
"I appreciate it a lot so thank you and I'm so happy they can extend their contracts and stay 10 years in the club."
