Sarfo, a midfielder for Swedish Premier league club Malmö FF, was found guilty of having sexual relations with a minor on two occasions between September 2016 and June 2017.
"The age of consent in Sweden is 15 and Sarfo, 23, was found to have on one occasion pursued the girl into a public restroom before raping her," read a statement in Swedish Publication, The Local.
Sarfo, who made his international debut for the Black Stars in a World Cup qualifier against Uganda last year has been ordered to pay a fine of R225 000 - while he is also set to be deported once his sentence comes to an end.
After the Malmo district court concluded their verdict on Friday, Sarfo's lawyer Mikael Sundman told a local newspaper that they are planning to appeal.
Malmö, 23-time league champions, posted a short statement on its website saying that it will address the issue when its board meets next week.
