Manchester City won the Premier League with 100 points in 2017-18
The Premier League is investigating Manchester City for allegedly breaching financial fair play rules.
On Thursday, Uefa said it was looking into "several alleged violations" concerning FFP at the club.
City claim the allegations are "entirely false" and on Friday, manager Pep Guardiola insisted the situation would not affect his legacy.
The Premier League now says it is investigating financial matters and academy player recruitment at City.
German news magazine Der Spiegel has published a series of claims, based on leaked documents, that Premier League champions City have violated FFP rules.
The publication also claims City made a banned payment of £200,000 to Jadon Sancho's agent when the England winger was 14 years old.
"The Premier League has previously contacted Manchester City to request information regarding recent allegations and is in ongoing dialogue with the club," a Premier League statement read.
"The league has detailed financial regulations and strong rules in the areas of Academy player recruitment and third-party ownership.
"We are currently investigating these matters and will allow Manchester City every opportunity to explain the context and detail surrounding them."
