Dimitar Berbatov - Tottenham Hotspur, Manchester United
This second generation professional footballer from Bulgaria made a splash when he transferred from Bayer Leverkusen to Spurs in 2006. But it wasn't until his 2008 move to The Red Devils that his true potential became clear.
Settling straight in at Old Trafford Berbatov marked his league debut with Manchester United with a quality goal assist to Carloz Tevez. Then he proved his £30.6m plus worth netting a Champions League double in October 2008.
