Osei began his career in 2001 with Ghanaian regional club Echomog and moved to Suhum Maxbees of the Poly Tank Division One League a year later.
He played for his third team in as many years in 2003, after transferring to Accra Hearts of Oak SC, before moving to Turkey to play for Akçaabat Sebatspor also in that year.
In 2004/05, Osei joined AS Livorno Calcio of Italy`s Serie A, going much unnoticed for the majority of the season.
The following season, Osei was loaned to FC Politehnica Timişoara, with the Romanian club having an option to buy him at the end of the season.
