Liverpool goalkeeper Pepe Reina has described Luis Suarez's 10-match ban for biting Branislav Ivanovic as "absurd and unfair".
The Spaniard has suggested that the FA "have it in for" his teammate, who is reportedly ready to quit English footbal over his harsh treatment.
He has previously been banned for eight matches for using racist language towards Manchester United defender Patrice Evra.
Reina told the Spanish radio station Cadena Cope: "I consider myself a friend of Luis. People in England are treating him different because he is Uruguayan; because he has had a previous episode like this.
"He knows perfectly well that what he did was wrong but a ten-game ban seems to me absurd, out of proportion and unfair. It seems that the people making the decisions have got it in for Luis a little bit.
"I know Luis and I know that he is the complete opposite: he is a magnificent person and great team-mate. But because of the way he plays, he is aggressive and very competitive, he plays like a street player and sometimes the way he is gets him into trouble.
"There is a lot of hypocrisy. Some players are treated differently to others. In the racism cases: the one with proof got a four-game ban and Luis got eight matches.
"I am not justifying what [Suárez] did but the punishment is very disproportionate. He knows he was wrong, he knows he has made a mistake but the treatment is completely out of proportion."
Asked if this could result in Suárez leaving Merseyside, Reina said: "Right now he is a Liverpool player. He is having a bad time of it and so is his family. He is certainly good enough to fit into any team in the world."
