Manchester City saw their ban overturned on Monday as their appeal to the Court of Arbitration for Sport (CAS) was successful. 'I'm happy with the way we act here. "The presumption of innocence was not there and after, when it happened and it was right, of course we are incredibly happy because we can defend what we have done on the pitch".
"People can not understand how hard it was for everyone as a club being under suspicion".
However, Guardiola feels it is City who are owed an apology.
This comes after it was discovered that most of the alleged breaches reported were either not established or time-barred.
"We have the right to defend ourselves when we believe what we have done is correct".
Jose Mourinho has given his view on Manchester City's appeal against a two-season ban from European football, calling the verdict "a disgraceful decision".
The club were accused of deliberately inflating the value of income from sponsors with links to the Abu Dhabi United Group, which is also owned by City owner Sheikh Mansour, to avoid falling foul of FFP rules between 2012 and 2016.
UEFA recognised in a statement that numerous allegations fell outside the five-year time limit in its own regulations.

The governor also ordered 30 counties to close gyms, churches, hair salons, malls and other businesses, according to the L.A. The counties with the highest number of cases include Los Angeles, Riverside, Orange and San Diego, in that order.
City's victory in court will raise fresh questions over how effectively UEFA can police FFP. If City are not guilty of it, then you are not punished with €10m. If you're not guilty you should not be punished. If you are guilty the decision is also a disgrace.
Guardiola also took aim at a group of nine Premier League clubs who reportedly wrote a letter to CAS to argue against City receiving a stay on their ban.
And Mourinho believes that in light of the City decision, any prospective new owners will not feel the need to comply with the regulations.
"I think it's better to open the circus door and let everybody enjoy".
FFP, which limits clubs to not losing more than 30 million euros over a three-year period, with exceptions for some costs such as youth development and women's teams, has helped drive down debt levels in European football.
Despite being permitted access to next season's Champions League, City were still hit with a fine of €10 million - a reduction from their initial sanctions of a two-season ban and €30m fine to the governing body.
"That will no doubt make Liverpool's job tougher next season but I think having all the competitions to focus on will make it an even keel for both".
