Grzegorz Rasiak
The Polish international joined Saints in a £2.7m move from Spurs midway through the 2005/06 season, but he produced his best form during the following campaign.
He produced some lethal form in front of goal and netted 21 goals in all competitions that helped Saints into the Championship play-offs, where they lost on penalties to his former side Derby County.
However, the 2007/08 seasons proved a struggle for both Rasiak and Saints and he was was shifted out on-loan to both Watford and Bolton.
A £1.62m transfer to Reading eventually materialised before he took moves to both Cyprus and then his homeland of Poland before retiring.
