Manchester City boss Pep Guardiola was angry about questions regarding financial fair play after their FA Cup final triumph over Watford.

The 6-0 demolishing of Watford at Wembley on Saturday added the FA Cup to last weekend's Premier League title and February's League Cup triumph over Chelsea.

However, this season's success could be overshadowed by allegations of financial irregularities with the club referred to the Club Financial Control Body adjudicatory chamber following a UEFA investigation.

Speaking immediately after the Watford win, Guardiola said: "From the beginning, this club has made a big step forward under Sheikh Mansour.

"There's no way you can do it without top players, money helps to buy incredible players. But I listen to my chairman, I listen to my CEO and they explain why they are under investigation.

"I trust them and when they tell me we were fair, we did it absolutely following the rules, I believe them. We are not guilty."
