Lamptey joined Venezia in Italy later was signed by Club Atlético Boca Juniors and went on loan at that same year at Unión de Santa Fe in Argentina. There, he and his wife had their third child, Diego. But soon, Diego died of a rare disease. A major emotional blow was also the fact that Lamptey wanted to bury his son in Ghana, but the authorities declined. Heartbroken, Lamptey temporarily gave up football. After unsuccessful stints at Ankaragücü and União Leiria, Lamptey got himself a new German player agent who transferred him to SpVgg Greuther Fürth. However, Lamptey and his wife were unhappy there, unable to live through the culture shock in Germany. Lamptey was not entirely unsuccessful, being a reliable backup, but was found too fragile for the rough Second Bundesliga. He was also reportedly ignored by his German colleagues, and once, a colleague flat out refused to sleep in the same hotel room as him. This blatant racism shocked Lamptey, but even worse was the fact that his child Lisa also died soon after birth. Also Lamptey's second dead child was buried abroad, in Germany. The Lampteys soon left for Asia.
