According to Spanish laws, only a sentence of two years or more are met with jail time, but Sanchez could still face further legal action if he is found guilty of a similar crime over the next 24 months.
The striker admitted his guilt and agreed to pay the Spanish authorities the money defrauded, plus interest.
Fernando Felicevich's statement expressed anger about "repeated, continuous and obscene leaks" of information from such cases in Spain, suggesting it pressures figures in football to accept agreements.
Felicevich accused the state and the tax office of applying the same means of pressure against players across Spain.
Sanchez's previous Barca partner Lionel Messi got a 21-month jail sentence, decreased to a €252,000 (£223,000) fine, to defraud the Spanish duty experts of €3.1m (£2.76m).
"Given the terrible experiences suffered by Messi, Ronaldo, etc have had to suffer, we concluded that it was better to accept an unjust agreement but be able to turn the page and not to be subjected to political and media pressure". "Almost the entire squad at Real Madrid and FC Barcelona have been put in this situation, as the clubs have used a means of paying tax that was accepted by the tax office in the past".
This isn't the first time we've heard of a Barcelona player going through the same ordeal as Alexis - with his former teammates Javier Mascherano and Lionel Messi also suffering the same fate.
