6. Nuri Sahin
Jose Mourinho signed him from Borussia Dortmund but then only gave him FOUR La Liga appearances.
Nuri Sahin was hotly tipped for a bright future after completing his move to the Bernabeu, but he simply couldn’t get into the first-team and never got to play regularly in Spain.
After struggling for three years, Sahin finally left the Spanish club and joined Liverpool on loan.
However, he went on to flop in England too and eventually returned to Dortmund.
