According to El Pais, he owes almost £3million in tax from 2006 to 2009, while he was at the Nou Camp. However the Cameroonian was all smiles as he was snapped with his wife Georgette in Milan.
Wearing a trendy scarf and flat cap with a gold watch, Eto’o and his wife were in a fit of giggles at one point.
As well as the long prison term, prosecutors are demanding he be fined around £12m.
Eto’o is accused of getting around tax through a complicated and illegal image rights structure.
He ran two companies — Bulte 2002 in Spain and Tradesport in Hungary — and this allowed him to transfer his image rights between the two and avoid having to pay tax.
Meanwhile, Spanish prosecutors are demanding current Barcelona attacker, Neymar, go to prison for five years.
