Manchester City boss Pep Guardiola believes it is up to Sergio Aguero to show he is worthy of a new contract.

The Argentine is one of the leading stars of this City team over the past decade, helping them to Premier League successes.

But the 32-year-old is at the tail end of his career, and Pep believes Aguero has to show he still has what it takes at the highest level.

Aguero played for City in their 1-0 win over Arsenal, his first appearance since being out for four months with a knee injury.

"Sergio now has to show, like every one of us, that he deserves to continue here - keep playing well, scoring goals and winning games - and after that the club and I will decide," Guardiola said of Aguero who is out of contract next summer.

"But if he is playing in his level we don't have any doubts that he is a player to stay until he decides because he is unique. He is important for us, our fans and everyone.

"But he was out four months and he has to start training regularly and start to score goals - this is the most important thing.

"Having Aguero on the pitch, we are better, we are safer. We missed him a lot in the important moments at the end part of last season, but now is good news for us that he is back."
