The 25-year-old spent four years in Germany with FC Schalke 04 but left last summer despite scoring 28 goals in 79 games. Mpenza spent the 2003/04 season with R. Standard de Liege and enjoyed a successful campaign with 21 goals in 28 appearances as the club finished third.
Mpenza, who was due to have a medical today, will cost a reported €2.5m. Schalke had to agree to the transfer as they had a clause which required Standard to ask permission before Mpenza could return to the Bundesliga.
Meanwhile, Hamburg have let versatile defender Milan Fukal join Bundesliga rivals VfL Borussia Mönchengladbach on a free transfer. The Czech international has signed a three-year contract. Fukal, 29, said: "I am really looking forward to playing for Borussia. I think the club has got a bright future."
