Pep Guardiola claims he would go to court to defend Manchester City's £100million signing of Jack Grealish.
City completed the British record acquisition of Grealish on Thursday after triggering a release clause in his contract at Aston Villa.
The size of the fee immediately raised eyebrows in some quarters over how the Premier League champions, who continue to be linked with another big-money move for Harry Kane, were remaining compliant with Financial Fair Play regulations.
Guardiola explained City have raised close to £60million in sales of fringe and Academy players recently, a figure which includes an £11million bonus from a sell-on clause activated by Manchester United's purchase of Jadon Sancho.
