Despite signing Riyad Mahrez, Manchester City are having a pretty quiet transfer window by their standards.

And with only a midfielder likely to be brought in before the Premier League starts next month, that theme will not change.

However, the Premier League champions could be set for a much more interesting transfer market in the near future.

The Breakdown

The Daily Mirror reports the club are considering cashing in on Raheem Sterling, who is valued at £81m by Transfermarkt, next summer if they cannot agree on a new contract with the 23-year-old.

Sterling's current deal runs until 2020, and Manchester City are wary about being left in situation similar to that of Arsenal's when Alexis Sanchez made it adamant he would not be signing a new contract at the Emirates.

With that in mind, it's a predicament that makes a sell sensible in some sense. That being said, Manchester City must do all they can to secure Sterling's long-term future at the club.

The England international has much room for improvement – his decision making in the final third and finishing in particular – but under Guardiola he has shown his value and is one of Manchester City's most dangerous players.

While he does come under heavy criticism for his lack of efficiency in front of goal, Sterling still managed to score 18 Premier League goals last season, with only team-mate Sergio Aguero, Jamie Vardy, Harry Kane and Mohamed Salah registering more.

Sterling also had the third highest amount of Premier League assists (11), further displaying how good he has become under Guardiola.

Manchester City would, of course, have the funds to easily replace Sterling, while the acquisition of Mahrez means a starting spot is far from guaranteed for the former Liverpool winger.

But Sterling has reached new heights thanks to the tutelage of Guardiola and should be kept at the Etihad.
